The Greenhouse Effect Protection is not a luxury, it is a necessity. It is important to understand the significance of the global warming, also known as the "Greenhouse Effect". The Earth is surrounded by a shield of atmospheric gases consisting primarily of nitrogen and oxygen molecules. The remainder of our air's composition is made up by a large number of "trace gases" that include carbon dioxide (CO2) and methane (CH4) which are also known as "greenhouse gases". The Earth is about 60 degrees Fahrenheit warmer than it would be if it did not have this atmospheric blanket of clouds and greenhouse gases surrounding it. Once warmed by the sun's radiant energy, these molecules radiate a portion of this heat energy back to Earth creating a warming effect on the planet's surface. Scientists call this radiation that causes the atmospheric gases to move back to Earth the "greenhouse effect". Carbon dioxide (CO2) gas generated by man's burning of fossil fuels and the forests is responsible for about half of the greenhouse gas warming. The ever increasing levels of these gases are the result of mankind's explosive population growth and increased industrial expansion over the last century. Global CO2 levels rise approximately 0.4 percent each year. Experts from the United Nations Intergovernmental Panel on Climactic Change predict that by the year 2070 global temperature levels will rise more than 5.4ºF to levels not experienced on this planet for more than 2 million years. Trees play a unique role in the global warming cycle in that they are the largest land based natural mechanism for removing CO2 from the air. Trees are able to store a large amount of CO2 in their structures. One tree alone can absorb approximately 13 pounds of CO2 per year. Each acre of forest absorbs approximately 2.8 tons of CO2 per year which is nearly 10 times more than the absorption of an acre of crop land or 20 times more than an acre of grassland. The average life span of a tropical hardwood tree is almost 200 years during which time an average rainforest tree will store up to 2,600 pounds of CO2. When a tree is burned however, the carbon locked in the structure is released into the air in the form of CO2 gas. Despite these alarming facts, each day more than 7,000 acres of rainforest are destroyed in the amazon region alone, amounting to more than 2.5 million acres each year. Most of this destruction is done by burning to clear the forest for homestead, roads, agriculture, mining and cattle ranching. The burning of this precious forest is said to be responsible for nearly 20% of our planet's green house gas emissions. We have been warned. In May, 1992 the first global study on the impact of The Greenhouse Effect on world harvests concluded that it would cause up to an additional 360 million people worldwide to go hungry by the year 2060, roughly 7% of the earth's human population. The time is near, just 64 years away! Our children may live to witness these devastating predictions. Today, results from this indiscriminate destruction is seen through the worst ever El Niño current that afflicts many parts of the earth with death and destruction. Strangely enough this phenomenon starts in the Pacific Ocean directly west of the Amazon region where water temperatures are as much as 40oF warmer than normal in early 1998 Within the next two hundred years, global warming will melt the polar ice caps, resulting in water levels that will flood and threaten to wash away present shoreline cities and resorts. Most smaller islands and popular destinations like Miami Beach, Cancun, Puerto Rico and Hawaii could become underwater relics. Some may one day be known as the "Atlantis" of the 22nd or 23rd centuries. Another consequence of population and industrial growth is Ozone layer depletion. The damage being done to the Ozone Layer of our atmosphere, if not somehow reversed, will force humans to wear protective clothing and eye goggles to avoid skin cancers and cataract blindness as early as the first quarter of the next century. Such high CO2 levels may even restrict human activities to indoor controlled air facilities. Gas masks would be required to venture outside. In fact, some cities have already recommended their use on days when air quality, now measured by weather forecasters in most large cities, is poor and air pollution levels are high. These are only some of the expected consequences . . . a far cry from the future as painted by Jules Verne and H. G. Wells. Coming generations face this dreadful future of gas masks and protective clothing. Would you like to help make it different? Would you like to become a part a team dedicated to reversing the trend and stopping the damage making the Earth a better place to live and the air cleaner to breath? If your answer is "YES" then together we can change our planet's destiny. Simply sign up as a sponsor/owner of M.I.E's Save the Rainforest programs. The quality of our tomorrow depends on our actions today.
