Where Have All the Forests Gone?
Where Have All the Forests Gone?
Scientists have discovered that forest trees offer unexpected help in the fight against climate change. Tropical rain forests are soaking up more carbon dioxide pollution that anybody realized. Almost one-fifth of our fossil fuel emissions are absorbed by forests across Africa, the Amazon and Asia, suggests Simon Lewis, a climate expert at the University of Leeds, who led a a laborious study of the girth of 70,000 trees across Africa.
David Ritter, senior forest campaigner at Greenpeace UK, said, “This research reveals how these rain forests are providing a huge service to mankind by absorbing carbon dioxide from our factories, power stations and cars. The case for forest protection has never been stronger.”
And yet we continue to cut them down across the world at an alarming rate!
What will happen when we lose natures best carbon filters?
As a nature nut, I feel compelled to address these very questions in this Earth Day lesson, because up until now, truly had not understood the serious impact we humans have had on the very things in nature that can save us from destruction, like rain forests …up until now, that is.
I’m grateful to have joined an incredibly talented and caring circle of people through on-line social networking who have inspired me to learn all about Earth Day, connect with the people involved in it and take action on what I’ve learned by celebrating Earth Day Birthday. This Earth day Lesson is written with the intention to inspire you to do the same.
Having just recently moved to Australia, I was fortunate enough to experience a wild rain forest filled with several waterfalls on a friend’s property. It was an experience that will stay with me forever because we can not feel the power of a special place like this and not intuitively know we have a duty to protect this amazing life form from destruction. The desire to share the spirit which envelops it is intense!
I intuitively knew I must share the experience, as well as my research as to what has been discovered about rain forests and their role in overcoming the challenge of global warming and the extinction of species.
Is “Deforestation” a Dirty Word?
It’s pretty easy to understand why deforestation has gotten a bad rap!
For example…
- Excessive commercial logging and clear cutting. These obvious moneymaking acts are rampant and the greedy business people make the bottom line their priority, regardless of its illegality and obvious wrong-doing.
- What happens to the animals! Trees are home to many species, including indigenous humans, who suddenly become homeless and often, extinct! Not to mention the demise of many plants which are natural wonders, many with healing properties.
- One major effect of deforestation is climate change. Deforestation has been found to contribute to global warming…the process when climates around the world become warmer as more harmful rays of the sun comes in through the atmosphere.
Changes to the earth as a result deforestation work in various ways:
One fact most people don’t realize is the abrupt change in temperatures it causes in the nearby areas. Forests naturally cool because they help keep moisture in the air. Some forget, also, about the water table underneath the ground. The water table is the common source of natural drinking water by people living around forests. Water table could dry up if not replenished regularly. When there’s rain, forests hold the rainfall to the soil through their roots, then the water sinks in deeper to the ground, replenishing the water table.
What do you suppose will happen when there are not enough forests anymore?
Water from rain will simply flow through the soil surface and not be retained by the soil. Or the water from rain will not stay in the soil longer, since the process of evaporation will immediately set in. Not good, right? I think we’d all agree that the need for drinking water is NOT negotiable.
So, if deforestation is so bad…why are we still allowing it?
Even though the word “deforestation” itself conjures up negativity and destruction, people don’t seem to realize that there are actually quite a few benefits of deforestation.
Just imagine what it would be like to live without the use of lumber. Wood is one of the most basic natural resources, and it is renewable simply by growing more trees. The trick is to balance it’s consumption by growing more trees to replace the ones removed. This is not, however, such an easy task.
With thousands of people losing their jobs, just imagine if the wood industry were to suddenly find themselves jobless. There are the people who cut down trees and process them and those who “clean up” after them. As forest is cut down, arable land becomes available for farmers, or used as an area to place urban living sites like apartments, houses, and buildings. If mandates are made for replanting trees, then jobs are also provided for the people performing that service.
With arable land being valuable for growing food, new land area provides a much needed place to grow a food supply to deal with the planet’s steadily expanding population of humanity. Additional living areas can be converted into more than just housing areas. Buildings can house offices for work, or factories to produce essential items, or even research facilities for things like new new medical or technological advances can end up in these deforested areas.
A colleague of mine, originally from Germany, would make a strong argument for forestry as a full time profession that can maintain a never ending supply of wood, as has been done in Europe for thousands of years. “In these forests, nobody clear cuts anywhere and trees are selectively selected while the rest of the forest remains and new tree-seedlings are put where the cut trees were. Europeans would probably argue that there are so many desert areas in the world that could be populated similar to the valley of the sun around Phoenix where no trees have to be sacrificed.”
Great arguments from both sides, so how do we proceed?
Let’s look at the REAL causes of Global Warming for answers
It comes full circle, back to carbon dioxide and the need for nature’s most effective carbon filter…forests.
Just think…Each time we drive a car, each time we use electricity from coal fired power plants, use natural gas or oil to heat our homes, we cause carbon dioxide (CO2) to be released into the atmosphere, as well as other heat trapping gases. The concentration of CO2 has increased by 31 percent since industrialization of our society and atmospheric methane gas has increased by 151 percent, caused mainly from agricultural activities like growing rice and breeding cattle.
As the concentration of these gases increases more heat is generated and trapped in the atmosphere. The increase in trapped heat alters our climate causing changed weather patterns which can bring unusually intense rainfall (precipitation) leading to flooding and severe storms, long dry spells leading to drought conditions and forest fires the like we just witnessed in the Australia Bush fires of 2009.
So what’s the solution?
There is no one best solution. Humans have been clearing forests over thousands of years for a variety of reasons. Obviously, as the statistics suggest above, much of the bad effects we experience today are happening at warp speed, so we really can’t afford to take our time in changing our ways.
Each of us can do something! Individually we can do small things…but together we can make a huge contribution to creating and implementing positive solutions. One has only to get on-line and Google the terms Earth Day or Earth Day Birthday to research, connect, watch, listen, take part and take action along with millions of other caring souls, government entities, non-profit associations and conscientious companies who are not letting any “grass grow under their feet”.
Earth Day, which was founded by U.S. Senator Gaylord Nelson as an “environmental teach-in” in 1970, is celebrated each year on April 22, mobilizing 200 million people in 141 countries and lifting the status of environmental issues onto the world stage.
Events are happening in every corner of the earth. Attend one!
Mankind needs Mother Earth. Mother Earth needs you to participate! Can you put aside just $10.00 for a gift to give your Mother Earth on her birthday, April 22nd, 2009?

Christians Earth Day
Christians Earth Day
Earth day is coming soon (4/22/09). This month we have Easter as well…so it got me thinking. How should Christians respond to Earth day?
First, I think we need to keep it all in perspective. Yes, we are to be good stewards of the planet. However, we are not to be earth “worshipers.” The earth is just another thing in our lives that God wants us to be a good steward with. Yes, it is important…However, Jesus Christ and His shed Blood is much more important. Saving souls should be above saving polar bears. You know what I mean?
So, do I think Christian’s should celebrate Earth Day?
Sure. Just make sure you have this whole eco, green planet stuff in perspective. Make sure that you are lined up with the Word and that God is your priority and His will. Do not let being green override sharing the Love of Christ and your true God-given purpose.
All that said, I thought it would be cool to add some fun stuff to do for earth day…
Earth Day Activities:
Plant a tree. This could be a fun family project.
Recycle. Take those cans you have been saving and turn them in.
Make the whole day green. Make eco choices all day long.
Clean up. Take your family to the park and clean up the junk left by others.
Make a point to add more green. Add at least one more green activity to your life.
Go on a nature walk. Enjoy the beautiful environment that God created for you.
Organic. Visit your local Ma and Pa farmer and shop for some earth friendly stuff.

Water Used in Generating US Electricity
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.

Go Green With Natural Finishes
Go Green With Natural Finishes
Finishes are coatings that are applied to the external and inside surfaces of walls to protect them from the elements and from wear and tear. They also improve the appearance of the structure and are used to enhance the design of rooms.
Petroleum, our main source of oil-based wood finishes and paint, is a non-renewable resource. There are now paints and finishes on the market that are derived from a renewable resource, which in a small way, helps to reduce dependence on oil, and contributes to a more sustainable world.
The basis for these products is whey, which is a product of cheese making, and which has a high biochemical oxygen demand (BOD). This increases the burden on waste treatment facilities, and can also pollute our natural water sources. In the last ten years, this by-product has been used for many new purposes, one of which is natural wood finishes.
When choosing paints for your decorating, use the low or no VOC (volatile organic compound) paints. For hundreds, no, thousands of years, earth, clay and lime have been used, both in hot and cold areas of the world. And now this knowledge is being readapted for contemporary use. If you do any redecorating or new building, it makes sense to contribute to having green, healthy surroundings.
Low and no VOC paints have less smell and less impact on air quality. EPA studies have shown that indoor air quality is up to five times more toxic than outdoors, mainly because of toxic emissions from paint and finishes. This particularly affects anyone with allergies, asthma, or chemical sensitivities. With the new “green” paints, there will be lower contamination of landfills, groundwater, and the ozone.
Switching will not cost you more. Cleanup is easily done with soap and water, instead of toxic chemicals, and brushes can easily be cleaned and reused. The paint is still washable, and is far less harmful to you, your pets, and the environment.

Historical Conservation Efforts
Historical 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.
