The Canada Pine Beetle
For some time now, the extremely destructive Pine Beetle ( Dendroctonus ponderosae ) is ravaging huge areas of Canada’s forestlands and its destruction is so virulent, that it is leaving massive and easily visible scars across otherwise green foliage landscapes. In numerous areas where the pine beetle is active, various solutions for its eradication have been tried and some of these in themselves, are so toxic in nature that they would normally be classed as being a larger risk than the beetle they are attempting to destroy.
These beetles have an average life span of about one year and generally, their eggs are laid through the bark of a tree where they develop into larvae that stay under the bark all through the winter months. During the spring the larvae continue to feed under the bark and then they will change into pupae during the months of June and July. During the rest of the summer and into fall, the new adult pine beetles leave the infested tree through emergence holes they create and after drying themselves in the warm sunshine, they take off to mate and commence a new cycle by laying the next generation’s eggs under the bark of new trees.
During the time they remain under the bark of a tree, they are known to transmit a fungus type substance that stains the sapwood of the tree a blue colour. Other than discoloration, this blue colouring appears to have no adverse affects on the actual structural integrity of the tree. However, we must not forget that the damage has already been done and like a rolling snowball, it gather momentum and range of spread with each summer that comes. These beetles prefer mature trees such as lodge pole pines which are considered mature after eighty years of growth and in the Province of British Columbia, current statistics show that there are three times more mature lodge pole pines than they had over ninety years ago. Hot and dry summers make the trees more stressed and thus more susceptible to attack and infestation by this ravenous little creature. Trees which have been attacked will turn red roughly one year after the infestation and then, between one and two years later the affected trees will turn grey and all of their needles will fall off.
Another interesting fact about these little guys is they do not like it too cold! Their eggs, larvae and pupae are very susceptible to very cold temperatures and if these temperatures remain below minus 35 Celsius for a prolonged period of maybe a week, then this will kill off the eggs, larvae, pupae and generally sizeable portions of the beetle population in that area of cold weather. This being said, unless we suddenly enter the start of a new ice age all across Canada, these sporadic cold spells are unfortunately not enough to rid us of this continually spreading plague of destruction. Yes, there are action plans prepared and in place and yes, the Canadian Ministry of Forests and Range are really trying to get to grips with finding a solution to this costly problem but to date, the efforts and methodology being used has had little or no effect on the overall problem.
The good news is that an answer to this massive problem does exist and better still, it is an answer, which consists of no chemicals, no toxins, no poisons and no danger to either the forest or to the people who would apply the solution. This answer can be found right now in the form of a golden all natural organic fluid formulated around a cedar oil base. This fluid can totally eradicate the pine beetle and a few other nasty insects at the same time. It is not cheap but then again it is not as expensive as some of the other treatment that have been tried. It is non hazardous and will not harm the environment in any way and it is here and available right now. Unfortunately, for now it appears that here it must stay as the Ministry of Forests and Range are continuing their quest with what they feel they know best. Maybe someday, hopefully soon, they will realize that we can defeat this natural pest by using a totally natural substance.

Gasification Sees a New Dawn
If you search for gasification and terms like “wood stove†on video sharing sites these days you will see demonstrations of wood being burnt in little stoves which seem to something almost miraculous and quite different from our idea of wood as a fuel. These little boilers light rapidly, produce no detectable smoke after the initial lighting and firing, and burn very hot.
So what is the technique which is being used, and how might it help us all in weaning society off fossil fuels?
What you have seen is a method of gasification. It differs from combustion in that it uses just 20% to 30% of the air or oxygen necessary for complete fuel combustion. During gasification, the amount of air supplied to the gasifier is carefully controlled with the effect that only a small part of the fuel burns completely. Trials of this process have illustrated that up to 70% of the energy value of the fue used can be recovered as what is known as synthesis gas, or syngas. This producer gas can also be used for various applications similar to natural gas.
This is a part of the magic, and not one really shown in the YouTube type videos, but it makes this method even more useful. This is due to the fact that syngas can be put to useful work, in both drying the feed fuel prior to gasification and after collection and storage it can be used as a fossil fuel replacement, and renewable energy source. When a gasification plant also includes Combined Heat and Power (CHP) and/or electricity export from the site, the gains are even more impressive.
Gasification in addition promises to be the most efficient long-term solution for capturing carbon while utilizing these valuable feedstocks, and storing the CO2 for very long priods, to reduce or halt global warming.
Gasification of wood and wood-type residues and waste in fixed bed or fluidised bed gasifiers with subsequent burning of the gas for heat production is has become state of the art with designers of thes systems working hard to gain the absolute maximum efficiency out of these systems.
These wood gasifiers which are located primarily in the Scandinavian countries are used almost entirely for space heating heat generation. Gasification of biomass is the renewable fuel system preferred by many, and can be defined as the thermal conversion of solid biomass to gaseous fuel.
Gasification has been around for over a hundred years, but the benefits of biochar are only now being discovered. Furthermore, it is still a wide-open field.
Before electric lighting was available in cities there were street lamps fuelled by gasified coal. It is easy to forget that the process has been reliably used on a commercial scale worldwide for more than 50 years in the refining, fertilizer, and chemical industries, and for more than 35 years in the electric power industry. More than 75 companies involved in the development, licensing, and use of these technologies as well as engineering, construction, equipment manufacturing and production of synthesis gas by gasification from coal, petroleum coke, heavy oils and other hydrocarbons.
Gasification has been proven to be a viable technology for CO2 capture and reducing SOx, NOx, particulate matter, and mercury emissions from coal and petcoke-fired power plants, synthetic fuels production, and chemical facilities.
Plants in this category have been capturing carbon dioxide for several decades in chemical plants in China and the United States. It also has potential contributions to make to both transportation and electrical power energy markets. With ongoing concerns about the price and availability of oil, populous countries like the U.S. gasification has proven to be in high demand and quite successful. However, it can also be used in conjunction with gas engines and gas turbines to obtain a higher conversion efficiency than conventional fossil-fuel electric power generation. Gasification can help meet renewable energy targets, address concerns about global warming, and contribute to meeting global environmental targets.
Steve has built a great web site where there is a lot more information about gasification. This is a hot subject indeed for this technology which has become an essential read for all those in alternative energy and interested in taking action to reduce the impact of climate change.
How Can Technology Help the Environment?
How can technology help improve the environment? Are we promoting a more singular existence, where individualism is the force that is driving us along? We are now living in a world that is in an accelerated mode of change and innovation. Is this rate of change detrimental to our existence? Think about this for a moment. On the one hand we have improvements in all areas of our lives some are greater than others. On the other hand we are looking at the effects of the harmful destruction of our planet earth.
The first computers started to emerge around the 1940’s, now we have computer processors in a lot of the electronic equipment we use every day. We even have computers that can fit in your hand that have more power than the first computers.The first Television and television transmission appeared in 1925 and now we are watching gigantic flat screens, some as big as buildings and others screens as small as wrist watches. In the past 80 years the medical field has also grown in leaps and bounds in the areas of IVF, genetic research, cloning, stem cell research, along with the progress in the prevention, cure and management of various diseases. Other fields such as astronomy, environmental science, weapons/warfare and engineering have also had their fair share of extraordinary development achievements.
Looking at the issues of Global warming and human environment interaction we are currently facing within our natural environment. Should we really be in a race to ruin the land where we live? We cannot keep up with the current technology, just look at all the equipment you have taken to the recycle tip in just the last 12-24 months. Consider how many Televisions, Videos, DVD players, Computers, Laptops, Hi-fi’s and Home entertainment systems you have changed or bought recently, the list is endless. When an improvement is made to a product it can sometimes make the original product obsolete. Satellite Navigation equipment a new and easily available product for everyone. Even if you only use it once a year it is believed to be a must have product. Mobile phones is another product every man and his dog has one these days. How often do you change your mobile phone for the latest model? Can you ever imagine being without a mobile phone? How did we ever cope without them? The raw materials used to make a phone cannot be recycled easily.
I believe as we get to understand one part(s) of our lives we seem to lose sight of others parts that are equally as important. What can be done to slow down the rate of change or how do we as a nation become more aware of the effects of the rate of change has on our environment.
If we could not have a new television or other new product until the old one had been recycled properly we would help the environment tremendously. Today if we implemented this many products or versions of products would be missed because of the speed at which technology changes. Like the latest flat screen with super clear picture quality. It seem that every other week we get the next new and improved product. Just look at washing power or washing up liquid advertisements.
Just some food for thought more to come soon.

Australia’s Emission Trading System
In Australia the government are introducing an emission trading or cap and trade scheme. There are major concerns about the level of reduction the government wants to sign up to and also whether it will actually work.
As Australians we do need to take action about carbon reduction. We are both the most vulnerable continent for feeling the effects of global warming and also we are the worst greenhouse emitters per head than any other country on the planet. We emit even more than the USA and Canada who are our nearest competitors for this wooden spoon. This is at least in part due to our huge coal industry.
The head of the Australia Institute’s Think Tank says that the Federal Government’s emissions trading scheme will have too many permits and will not reduce carbon emissions.
The Australia Institute’s executive director, Dr Richard Denniss, said the scheme’s flaws related to the 5 to 15 per cent emissions reduction targets, which he described as ”ridiculously low”, and he said there would be too many permits. Dr Dennis said that “We won’t achieve the policy goal, which is to reduce emissions.”
Dr Denniss told the Senate that ”[If] we pass this legislation, we’ve got it for the next 10 years. And anyone that’s got a good idea a year later, it’s not going to help. This legislation is designed to not be tinkered with.”
Professor Clive Hamilton, from the Centre for Applied Philosophy and Public Ethics, said the proposed scheme had damaged Australia’s reputation. A reduction target of at least 25 per cent needed to be set if the Government wanted credibility on the world stage. Australia would be better off taking no policy than the proposed model to the December climate change talks in Copenhagen, he said.
”It not only lowers the ambition of the world community but also excludes Australia from being a forceful player in negotiating … a strong international agreement.”
It is hard to see how exempting large emitters ignoring the 1.9 million small to medium businesses is going to help us reduce our carbon footprint. These same small businesses are currently suffering from financial stress, the business owners and managers are overworked and simply don’t feel able to handle anything new. Many don’t really understand what global warming is about or why it matters.
We urgently need unambiguous communication so that small to medium businesses accept the reality of the need for change and also how easy it can be to make significant reductions with minimal time input and save money at the same time.
We also need to help low income households reduce their carbon footprint with more efficient heating and cooling and effective public transport. We should NOT be giving them even more cash hand outs as “compensation” as currently promised by the government. All households need to come on board and stop wasting power.
We need a clear message that going green applies to all of us, is easy and saves money – just “go for a grumpy walk and just turn it off”. If every small business and householder just went around each office and home and did this it would be relatively easy for every one to reduce their carbon emissions and their power bill by 15-20%. At present we are told it will be difficult and it only applies to big business. Such a wrong message – we all need to pull together.
A Brief given to the Victorian Government advises that the state should only bother with green measures if they are more cost-effective than alternatives. They have been told to rethink programs such as subsidies for solar farms and hybrid car fleets because these will not contribute to any additional emission cuts under the federal scheme.
The Greens have concerns about the cost of emission permits being reduced by the actions of households, councils and governments, hence reducing industry’s incentive to cut emissions. This is more than simply an economic debate. Individuals and households should also be reducing their emissions. Achieving sustainability is a grassroots exercise that involves the entire community, and Australians are becoming aware of the need to remake the economy and society. The momentum must not be lost.
An additional concern is whether the legislation and also the international agreements reached in Copenhagen will be flexible enough to take account of emerging technology. At present this does not appear to be the case. Senator Wong, the Minister for Climate Change, rejected spending on biochar, a form of carbon capture in soil research because that is not listed in the protocol. Thankfully some soil carbon storage research will now be funded in the agriculture budget but that begs the requirement for the legislation to be flexible and allow for new and future technology.
If the ETS cannot deliver real carbon reductions it is really a form of “greenwash” saying we signed Kyoto and have done something before the next election. The big problem is that the government looks ahead 3 years to the next election, Big Biz CEO’s also look to the short term of their contracts and bonuses. Who looks ahead for our children?

Antarctic Peninsula Climate
Antarctic Peninsula has been experiencing warming trends for over 40 years with an increase of 2-3 C, thus correlating with lower sea ice conditions in the Amundsen Sea and Bellinghausen Sea. Warming temperatures around the Antarctic Peninsula is changing the dynamics of the ecosystem. The rise in atmospheric temperature is causing increasing in melting of freshwater glaciers and ice shelves. Fresh water emerging into the sea counteracts the salinity within a regional area. Changes identified are;
• Decrease in sea water salinity up to 60 miles offshore
• Lower sea ice
• Decreased krill population
• Increased salp (open ocean tunicate that is reminiscent of a jelly-fish) population
• Increase in cryptophytes (single cell phytoplankton algae)
• Decrease in diatom phytoplankton
• Increase in carbon sequestering in deep ocean sinks
• Decrease in carbon availability in the food chain
The Antarctic Krill (Euphausia superba), a small shrimp like crustacean is the most important zooplankton species associated with the sea ice and plays a crucial role in the Antarctic food web. On a regional basis the amount of krill appear to be declining in the southern ocean. There are definitely lower trends in krill population during lower sea ice years around Antarctica. Part of the rational for the population decline is that ice algae rely on the sea ice for protection and growth. The krill need the sea ice in order to feed on the algae and phytoplankton.
Krill occur in groups or large swarms. They are less than 3 inches in size and feed primarily on phytoplankton and sea ice algae. Krill filter diatom phytoplankton out of the water column and scrape algae from the sea ice. Apart from frequenting the sea ice to feed, krill in particular juveniles, seek protection from predators in the many nooks and crannies formed by the deformed sea ice floes. Krill is the staple food of many fish, birds and mammals in the Southern Ocean. The biomass of Antarctic krill is considered to be larger than that of the earth’s human population.
Sea- ice algae utilizes atmospheric carbon dioxide for its energy source, the same as plants do on land. Krill diet of the sea-ice algae and phytoplankton is essential for converting the carbon for use in higher animals such as fish, birds, and whales. This carbon conversion is a very critical role in predatory nutrition. Additionally krill do eliminate some of the silica from the diatom shells and carbon in sticky balls that sinks nearly two miles into the deep ocean. These cold, deep waters are able to contain carbon dioxide and prevent the gas from rising to the surface, thus immobilizing carbon that is not passed into the food chain.
In recent years there have been increases in algae phytoplankton called cryptophytes. Mark Moline, California Polytechnic State University, states that the cryptophyte population correlates with warmer temperatures and lower salinity waters that are produced by the melting of the freshwater glacier. Cryptophytes measure around 2 mm, while other plankton in the Antarctic waters are much larger and measure 15 to 270 mm. Along with the increase in cryptophyte population an increase in salp, a pelagic tunicate, population has also occurred. There are differences between salps and krill. Salps feeding efficiency is capable of grazing on smaller food sources less than 4mm, whereas, the Antarctic Krill efficiency declines on any food less than 20 mm. The salps compete with krill for the phytoplankton and thus decrease the krill population. Additionally the salps feed on krill larvae, which also cause a decline in krill numbers.
The warming trend in the Antarctic Peninsula is showing a pattern of increasing cryptophytes over other phytoplankton and the increase in the salp. This influence is due to the low sea ice and the lowering of the salinity in the seawater. Salps and cryptophytes do better in the lower salinity, while the krill and other plankton are unable to tolerate the increased freshwater regime from the glacier ice melts. This selectivity gives preference to the salps as the dominant species while decreasing krill abundance. During lower sea ice seasons the density of krill declines while the salp population increases.
Carbon sequestering into the deep ocean from the algae and phytoplankton occur by both the salp and krill. Both species eliminate the atmospheric carbon received from the primary producing algae by producing fecal pellets by the salps and sticky balls by the krill, thereby, reducing the amount of carbon dioxide in the atmosphere. The salps though sequester more carbon into the cold deep ocean than the krill. However, the krill provides the most efficient pathway for carbon transfer up into the food chain. The cryptophyte dominated waters are less efficient in the food chain due to increased feeding by salps and the difficulty of the krill to utilize the cryptophytes as a food source. Migration patterns by penguins are changing, in part due to the changing krill population. Krill is a mainstay diet for penguins, and if the krill population changes, many other ecological changes occur with it.

Water Efficiency – Water Used in Generating US Electricity
In my four-article series on water use (The Resource Matrix), I took you on a journey to reveal the layers of The Resource Matrix in order to help you understand how water will be a highly contested commodity tomorrow, possibly as much as oil is fought over today.
You learned about your water footprint and a website where you can calculate it, virtual water and virtual water transfers, whereby choices here affect water availability elsewhere, to the point of some people not having enough water to drink in order to produce inexpensive dyed cotton, along with insane choices such as growing crops in the desert.
You learned that on average it takes 1854 to 3000 gallons to produce one pound of beef.
Yep, it’s it’s been a great journey through the sidetrip city of the Resource Matrix.
Today, we’ve found the on-ramp to the Green Lighting Interstate and are driving to take a look at water use in generating electricity.
For a simple reason. It takes a lot of water to produce electricity.
How much? 5% of all US water? 10%? Can’t be as high as 25%?
Electricity and water?
I thought the issue was fossil fuels and greenhouse gases
The U.S. Geological Survey (USGS) estimated water use in the United States in 2000.
Their grand total: 408 billion gallons per day withdrawn for all uses.
The number 1 spot, weighing in at 48%, was thermoelectric power.
Irrigation earned the runner-up prize at 34%.
The 195 billion gallons need to come from somewhere, and actions have consequences. Environmental ones, as in 40 million fish in the Great Lakes killed each year due to being trapped against water intake devices. That’s a lot of Friday night fish dinners.
How much water is used in generating electricity?
Large fossil fuel and nuclear plants require incredible quantities of water for cooling and ongoing maintenance.
Water for thermoelectric power is used in generating electricity with steam-driven turbine generators. It uses 48% of all water in the US.
According to the Pace Energy and Climate Center, the amount of water used for power plant cooling varies by each specific power plant’s electricity generating technology and size. Nuclear reactors require the most water for cooling, and baseload fossil fuel power plants come in second.
The Salem Nuclear Generating Station alone takes 3 billion gallons a day from the Delaware Bay, according to the Pace Energy and Climate Center.
Nationally:
- Steam electric generating plants across the nation draw in more than 200 billion gallons per day.
- Nuclear and fossil fuel power plants drink over 185 billion gallons of water per day.
- Geothermal power plants add another 2 billion or so gallons a day.
- Most renewable energy technologies require little or no water for cooling.
These numbers are starting to sound like the same ones the U.S. Treasury and Federal Reserve Bank use.
Imagine watching your favorite science program where astronomers explain that the universe is 78 billion light-years wide (78 billion units of 5,878,630,000,000 miles). There is absolutely nothing in our experience to help us wrap our mind around it.
How much is 3 billion gallons per day?
The Delaware Bay feeds Salem Nuclear Generating Station 3 billion gallons a day.
Imagine this rectangle: a football field with end zones (360 feet long x 160 feet wide). Then add to it walls on each side of the rectangle to create a container to hold the 3 billion gallons you pour into it.
How high do you need to make those walls to contain 3 billion gallons? 6915 feet high. Or 1.3 miles.
Maybe 6915 feet high is still hard to imagine. So how deep do you cover the field in order to feed the Salem plant every minute? Answer: 5 feet deep. Every minute.
48% of all water use: We’re Number One!
How much is 195 billion gallons per day?
Using the USGS figure for 2000, thermoelectric power nationwide used 195 billion gallons a day, or 48% of all water used in the US. My guess is the water use has grown since then.
How high are the walls on our football field now? 449,475 feet or 85 miles high. We’re back to US Treasury and astronomy numbers again.
So, let’s get a higher-level view to help us.
Lake Erie holds 116 cubic miles of water.
Nationally, thermoelectric power uses 195 billion gallons a day – or 64.2 cubic miles a year.
We drain Lake Erie every 22 months.
But the water used is returned to its source.
So what’s the issue about water use?
Power generation returns 98% of the water back to its source (bay, lake, river, ocean).
It’s the environmental consequences.
The Pace Energy and Climate Center explains it neatly:
Withdrawal of large volumes of surface water for either power plant cooling or hydropower generation can kill fish, larvae and other organisms trapped against intake structures (impinged), or swept up (entrained) in the flow through the different sections of a power plant.
Examples include:
- The Salem Nuclear Generating Station is responsible for an annual 11 percent reduction in weakfish and 31 percent reduction in bay anchovy.
- At the Indian Point 2 and 3 reactors on the Hudson River, the number of fish impinged totaled over 1.5 million fish in 1987.
- The 90 power plants using once-through-cooling on the Great Lakes kill in excess of 40 million fish per year due to impingement. (Once-through cooling needs a continual flow of new water, and uses 30 to 50 times that of a closed cycle system. Closed cycles cool down water from steam then reuse it.)
The diversion of water out of the river removes water for healthy in-stream ecosystems:
- Stretches below dams are often completely de-watered.
- Fluctuations in water flow from peaking operations create a “tidal effect,” disrupting the downstream riparian community that supports its unique ecosystem.
- A dam’s impoundment slows water flows, which hinders natural downstream migration of many fish species.
- By slowing river flows, dams also allow silt to collect on river and reservoir bottoms and bury fish spawning habitat. Silt trapped above dams accumulates heavy metals and other pollutants. Disrupting the natural flow of sediments in rivers also leads to erosion of riverbeds downstream of the dam and increases risks of floods.
- The impoundment of water by hydropower facilities fundamentally reshapes the physical habitat from a riverine to an artificial pond community.
- This often eliminates native populations of fish and other wildlife.
- Dams also impede the upstream and downstream movement of fish and other wildlife, and prevent the flow of plants and nutrients. This impact is most significant on migratory fish, which are born in the river and must migrate downstream early in life to the ocean and then migrate upstream again to lay their eggs (or “spawn”).
- As mentioned above, withdrawal of water into turbines can also impinge or entrain significant numbers of fish.
The cleanest kilowatt is the one never used:
Back to those compact fluorescent lamps and LEDs
PowerScorecard.org explains the solution:
By re-directing electricity dollars to support environmentally benign energy resources, consumers are empowered, in states that offer supply choice, to influence the existing generating resources that are deployed to meet demand.
They can also support the construction of new and cleaner electricity resources that will be built to meet overall growth in demand in the future. By supporting these power options, consumers can minimize many water use and consumption impacts. Still, directing your dollars to cleaner power products in no way helps remediate damages that already have occurred. Consumers can stop the construction of new hydropower facilities or alter conditions of siting and operation, but they cannot undo previous environmental degradation that occurred at existing hydropower facilities.
In short, reduce your use of electricity.

Conservation Efforts
How often have we come across lovely historical sites suffering from neglect and misuse? Every country needs to take good care of its historic places. Because things like malls, stadiums and highways can be built again. But a historic place which is neglected and misused will lose its glory and slowly disintegrate into zilch. And no amount of action plan or noble intentions can ever bring a historic place back to its former glory when it has been totally neglected and abused by us. The oldest of historic sites can be preserved for the future generations if we have a proper plan for their conservation.
Conversation of historic places requires a systematic approach. If the historic site is conserved with the help of a proper plan, it will show amazing results. While chalking out a plan for the conservation of historic sites, it’s very important to keep the costs under control. If the costs go up to an unwanted level, it will draw criticism from the general public and act like a death sentence for the conservation of other similar projects in the future.
The first thing which should be done by the restoration experts is to check the age of the historic site. This can be easily achieved by conducting a series of scientific tests. It can also be done if there are public or archaeological records of the site. Once we know the actual age of the historic site, we get to know the actual worth of the site – this doesn’t mean that if a site is not very ancient – it’s not worth taking care of.
Also check the sturdiness of the materials which have been used on the historic site. This will need a proper list of all the materials used on all the structures found on the site. Factors such as the effect of temperature, humidity, weathering, fire, air pollution, storms and flood on the material found on the site needs to be studied in detail, so that best possible plan to prevent further degradation of the site can be prepared.
Don’t forget to note the architectural design of any structures present on the site. This is needed to take help of conservation experts according to the style they specialize in. Taking the help of the best of experts who are not competent in the architectural design displayed at the historic site would create a major problem for your conservation project.
Your team of conservation experts also need to keep a track of all the past repairs and changes made on the historic site. The problems faced by the previous restoration team while restoring or repairing the historic site too needs to be researched and noted down. Always remember materials like wood and leather rot quite easily, on the other hand stone articles and pottery items always manage to survive better. Once you have finished your complete study of the historic site, you can then do the restoration part of the site step by step in a phased manner till it is complete. You might even have to restrict the number of visitors, once it has been restored, as although the site has got its former glory, it might not be in a state that it can be exposed to an endless number of people everyday.

The World Energy Crisis
The world has some decisions about sources for future energy. The increase in population and increasing demand present a problem. The cost of conventional non-renewable energy sources is on the rise. Oil, gas, water, coal, and other natural resources have a limit to their supply.
Gas, Oil and petroleum products are more expensive than ever, and the supply is running thin. Many may think that the planet may never run out of these however it seems that drilling these supplies is becoming ever more difficult. There have been three major energy crises thus far.
Due to the shortage of resources and decreased output, the cost of these energy sources has increased rapidly over the years.
How long will it take before all of these resources are exhausted? The truth is that we really do not know. Experts say that 50% of the world’s supply of available oil has been exhausted. Every day the demand is increasing and it could take mere decades to exhaust the supply of crude petroleum.
What could possibly be done about this situation? How can we as a society cope with the energy crisis at hand? What can we consumers do about this? We can all start by understanding the importance and impact that energy has in our lives. These supplies of energy should not be taken for granted. Additionally we should avoid wasting energy.
There are simple things that we could do to conserve such as getting involved with a car pool, check our car tires for proper inflation, and using fuel efficient vehicles. If we can cut down on our use of fuel and oil in everyday activities we can be further prepared for the impending energy crisis.
Another way that we can cope with the energy situation is by utilizing renewable energy sources. Solar and wind power systems are becoming ever more available. These power solutions are feasible, cost effective and environmentally friendly. In addition, you save on your power bill and help contribute towards a better future for our world.

Strong Radical Anointed Leadership is Greatly Needed
The environment, which its current emphasis on ‘Global Warming’ and ‘Climate Change’ important though it is, is not the most vital matter facing humanity.
During recent speaking and teaching visits to Uganda and Kenya, and hearing something of the actual situation, I have become angry and occasionally tearful at the gross injustice, greed and corruption which is rife.
Our world has become so unstable over these past months in a way totally unpredictable by man. If I had written prophetically, 15 months ago, about what we are presently experiencing in the area of finance, you would have said I was off my head and just daft!
The Carbon Footprint issue might be causing some environmental damage although is being question by many, but the financial greed and mismanagement footprint is hurting millions as people loose income, jobs, houses and basic security.
When I was in Kenya last November, I was informed that the economic problems hitting America and Europe would hit Africa in three months time, and visiting schools and orphanages in the various slum areas I was very much aware of how a little extra resources could help so many more people with very little effort.
The structures are in place to utilise and distribute AID in a responsible manner. I have seen the projects designed to help those whose lives are confronted with unnecessary suffering, one example of this in Methere in Nairobi and the River of Life School in Manyatta, Kisumu. Now, there are other projects and schemes in various other nations and by investing in these immediately, the environment would improve slightly within a few months, but for the people who live there the improvement would be immense.
I write this as the G20 Summit is meeting in London. The money spent on that alone could feed the poor in Kenya (or some other nation) for months. It is just that I know a little about Kenya.
Earthquakes, floods and droughts will continue, and these will undoubtedly increase, with environmental disaster and tragedy resulting, but what concerns me is the area where substantial and significant improvements could be made, if only leaders would make sensible wise decisions.
You see, I write as a committed disciple of Jesus Christ, and I am not given the option of being quiet on these issues.
One sentence really challenged me this week. If you were reading the Sermon on the Mount for the first time, in Matthew’s Gospel, Chapters five to seven, how would you change your life?
How might this motivate us in the areas of fresh water and sewers, immunisation and basic health services, and feeding programmes and education for those who genuinely want to study and contribute positively towards the welfare and well-being of their nation.
To make these environmental improvements, strong, radical leadership will be required, but it is often in times of real darkness that the risen and living Lord Jesus Christ chooses, redeems, and raises up a leader or leaders to shepherd people out of their predicament.

Water Efficiency – The Resource Matrix Part 2 of 4 – Water’s Role in Global Warming
Last week, we introduced you to the Resource Matrix, which is everywhere, it is all around us. It is the world that has been pulled over your eyes to blind you from the truth.
We showed you how economics leads to people maximizing their benefits in “win-lose” propositions: you want diamonds and gold for nothing and they want to give you useless junk for a king’s ransom. And how we’ve been hypnotized in believing what they want is also what we want.
But the scales have been falling from our eyes, we’re beginning to see the truth, and the power has been shifting away from the “I want your goodies for nothing” crowd:
- Do-gooders have increased our awareness and worked to change deals from “win-lose” to “win-win”
- There is no “free lunch:” finite energy resources will run out; actions have consequences, and the consequences of our actions are already visible, rather scary, and quite irreversible; and that the “I want your goodies for nothing” crowd hasn’t been telling the truth
We now realize we’re all in this together: we have greater awareness of our actions and the desire to change, and have ways to change.
Hallelujah and Praise the Collective!
Today, we introduce the resource called water, its parallels with fossil fuels, and its role in global warming.
None of this is to dismiss or diminish the contribution of fossil fuels in global warming. Hey, just like the Special Olympics, if you participate, you get a medal. We just think that gold-medal winner Fossil Fuels has stolen the spotlight, letting silver-medalist Water Use keep us hypnotized in believing that water is a free lunch, and that nature will clear up polluted waters while getting away with breaking the rules.
Water, water, everywhere,
not a drop to drink.
According to our friends at How Stuff Works, who I wrote about sarcastically for their oxymoronic clean coal article in discussing how true public relations stuff really works, gives us this data:
- 98% of the planet’s water is in the oceans. It’s salt water – we can’t drink it or irrigate our crops with it.
- 2% is usable. Of that 2%:
- 80% is locked up in polar ice caps and glaciers
- 18% is underground in aquifers and wells
- 1.8% is in lakes and rivers
- 0.2% is elsewhere: either floating in the air as clouds and water vapor, locked up in plants and animals (and your body), and in foods and beverages.
Okay, so 20% of the usable water (only 0.4% of all water on Earth) is accessible, right?
Well . . . no. Many of the aquifers, wells, lakes, and rivers have been sucked dry like a once-juicy fly carcass in a spider’s web. (The 18% and 1.8% you see above is like the money in the Social Security Fund: there actually is nothing there.)
And many of those water sources that do still have a drop to drink are worse than the ocean’s salt water. Drink salt water and you’ll need to yawn into a bucket. Drink this water and you’ll kick the bucket.
And I know you aren’t asking this burning question:
“So . . . global warming to release fresh water from ice caps and glaciers is a good thing, no?”
Percentage this, percentage that.
Talk my language, will you?
I know I’m pulling the disgusting old government trick: drowning you in an ocean of water statistics.
So let’s make it plain and simple:
You bring in $10,000 a month. You’re also living high on the hog and doing your personal best to outshine every bling-bling Hip Hopster Musical Artist in materially conspicuous consumption:
- $9800 goes to the McMansion mortgage and gold-plated Rolls Royce lease
- $160.00 goes to investments in clothing and accessories
- $0.40 has been lost in the sofa cushions
- $39.60 a month is for everything else: food, phone and electric bills, income taxes, and all the other non-essentials: Don’t spend it all in one place!
Aquifers and wells and lakes and rivers:
Dry or polluted, oh my!
Fred Pearce, author of When the Rivers Run Dry, helps us quickly understand it:
We can all save water in the home. But as laudable as it is to take a shower rather than a bath and turn off the faucet while brushing our teeth, we shouldn’t get hold of the idea that regular domestic water use is what is really emptying the world’s rivers. Manufacturing goods … consumes a certain amount, but that’s not the real story either. It is only when we add in the water needed to grow what we eat and drink that the numbers really begin to soar. (emphasis mine.) (Fred Pearce, When the Rivers Run Dry, Boston: Beacon Press, 2006. p 3)
Here are a few numbers he gives:
- to grow a pound of rice: 250 to 650 gallons of water
- to grow a pound of wheat: 130 gallons
- to produce a quart of milk: 500 to 1000 gallons
- to produce a pound of cheese: 650 gallons
- to produce a 1/4 pound of burger: 3000 gallons
He kindly puts water use into perspective in annual terms:
- 1 ton (265 gallons) for drinking
- 50 to 100 tons (13,250 to 26,500 gallons) around the house
- 1500 to 2000 tons (397,500 to 530,000 gallons) for food and clothing

How Many Gallons to Produce One Pound of Beef?
Lies, damned lies, and statistics
US Beef industry’s Cattlemen’s Association: 441 gallons
Fred Pearce: 12,000 gallons
Water Footprint Network: 1854 gallons (calculations: 15500 litres of water per kg; 4079 gallons per kg; 1854 gallons per pound)
In an industrial beef production system, it takes an average three years before the animal is slaughtered to produce about 200 kg of boneless beef.
The animal consumes nearly 1300 kg of grains (wheat, oats, barley, corn, dry peas, soybean meal and other small grains), 7200 kg of roughages (pasture, dry hay, silage and other roughages), 24 cubic meter of water for drinking and 7 cubic meter of water for servicing.
This means that to produce one kilogram of boneless beef, we use about 6.5 kg of grain, 36 kg of roughages, and 155 litres of water (only for drinking and servicing).
Producing the volume of feed requires about 15300 litres of water on average.
—————————————–
Where does all that water come from?
From virtually everywhere
If it comes from imported goods (Thai rice or Egyptian cotton), the water comes from those countries.
When the water is collected from rivers or pumped from underground, as it is in much of the world, it’s:
- increasingly expensive
- increasingly likely to deprive someone of water (nothing to drink)
- increasingly likely to empty rivers and underground water reserves
And when the rivers are running low, as they are more frequently, there is less water to grow anything at all.
The water used in growing and producing goods around the world is known as “virtual water” and the trade of these goods is known as “virtual water transfers.”
And who’s the biggest water exporting Mouseketeer of them all? The United States.
When you drink coffee from Central America, you are influencing the hydrology of the region, virtually taking a share of the Costa Rican rains. The same is true within a national and regional boundaries. The Colorado River is drained so Californians can eat their Big Macs and have friends over for a Sunday afternoon barbecue.
In the same way that your use of fossil fuel is measured as a “carbon footprint,” your water use, actual and through virtual water transfer, is measured as a “water footprint.”
How big is my water footprint?
I’ll show you mine if you show me yours
Arjen Y. Hoekstra, professor at the University of Twente, the Netherlands, introduced the water-footprint concept in 2002. It “shows water use related to consumption within a nation, while the traditional indicator shows water use in relation to production within a nation.” (Hoekstra and Chapagain, Globalization of Water, Malden: Blackwell Publishing, 2008, p. 3)
With Hoekstra and Chapagain’s water footprint calculator (waterfootprint.org), you select your country, input food, domestic water use, and industrial goods consumption, press a button, and you get your:
- total water footprint for the year
- bar charts for the three components
- bar charts for individual food categories
For example, you’re in the US, eat only 1 pound of cereal a week (.4545 kg) and have a low-fat, low-sugar diet, use a low-flow showerhead, use a no-flush eco-toilet, and never run the tap while brushing your teeth. Two extremes:
- You’re the hippiest of the hip: making $10,000 a year: Your water footprint: 245 cubic meters (65,170 gallons)
- You’re the hippiest of the Yuppies: making $120,000: Your water footprint: 2979 cubic meters (792,414 gallons). Difference due to your income’s effect on industrial production.
Three notes on the calculations, because Professor Hoekstra is European and lives in the social welfare country that started birthing hippies in Amsterdam decades before they showed up in the US at Woodstock:
- You input kilograms for food:
- 1 kilogram = 2.2 pounds = 35.2 ounces
- 1 ounce = 0.028 kilograms. 1 pound = 0.454545 kilograms
- Your water footprint is in cubic meters per year:
- 1 cubic meter = 35.3 cubic feet = 266 gallons
- The higher your income, the greater your water footprint, even if you don’t personally consume anything: you’re a capitalist pig supporting the Establishment Regime, I guess
So how is Cinnamon’s capitalist water footprint? Answer: 650 cubic meters (172,900 gallons)
I showed you mine. Now you show me yours:
Get the naked truth: Calculate your waterfootprint now:
Water’s running out:
I get the fossil fuel analogy so far.
And what about climate change?
We return to Fred Pearce’s book to find an example, of which he has oceans:
China’s Yellow River: The fifth longest in the world, it begins high in the mountains of eastern Tibet and journeys more than 3000 miles. Almost half a billion people depend on it for drinking and crop irrigation, and it’s made China the world’s largest wheat producer and second largest corn producer. Yet more than half of the lakes it feeds have disappeared over the last 20 years, and a third of pastures have turned to desert. This desertification generates huge dust storms that choke lungs in Beijing, close schools in Koreas, dust cars in Japan, and rain dust on mountains across the Pacific and Western Canada.
State irrigation projects along the Yellow River soak up the majority of its water – the total official allocations are greater than the actual flow.
The resulting drought could be an early warning sign of global warming.
Much of the declines in moisture reaching rivers is in line with prediction of climate researchers. So how does this global warming happen?
Higher air temperatures from desertification increase evaporation from oceans and intensify the water cycle. This increases atmospheric water vapor – 8 to 10% more than today. This increases global rainfall, but the rain is being redistributed: middle latitudes (read: the US) are becoming drier. Higher temperatures increase evaporation on land, meaning soil dries out faster, meaning less rainfall is reaching rivers.
The higher temperatures melt glaciers and snowpacks. At first, this leads to unpredecented floods. After the glaciers disappear, meltwaters that feed rivers disappear. The combined decreasing rainfall and increasing evaporation will lower moisture by 40% in the southern and western states.
The Sierra Nevada snowpack could diminish by 70 to 80 percent over the next 50 years. And some of the world’s most productive agricultural regions could dry up.
Global climate is becoming more extreme: the dry areas become drier, and the wet areas become wetter. And more areas are becoming dry deserts. Loss of habitat and agricultural lands. It’s a vicious cycle.
So what can you do?
Navigating through the Resource Matrix
As Fred Pearce points out, your drinking and bathing account for 0.05% of your total water consumption. Your food and clothing weigh in at 95.00%, although I find his 12,000 gallons needed to produce a pound of burger rather wild.
As Professor Arjen Y. Joekstra shows with his Water Footprint Calculator, your consumption of meats accounts for a lot, as does your guilt by association of being in an industrialized country.
The obvious solution: eat fewer e-coli burgers from your neighborhood Salt and Fat Slop Bucket restaurant.
The wiser solution: like your choices in energy use, become more aware of the resources needed to produce anything and the consequences. Such as luxurious cotton grown in the Egyptian desert.
