Over 5500 acres of rain forest destroyed daily
Trees are able to store a large amount of CO2 in their structures. An acre of forest will absorb about 10 times the CO2 amount absorbed by an acre of crop land or grassland. One tree absorbs about 13 pounds of CO2 per year, and each one acre of forest absorbs about 2.8 tons of CO2. However, when trees are burned, the carbon locked in the structure is released into the air in the form of CO2. Today, the shrinking world forests are not able to absorb all the CO2 created by human beings while burning fossil fuels. Everyday over 5500 acres of rain forest are destroyed, and over 50 million acres are destroyed every year. Global CO2 levels rise approximately 0.4 percent each year, to levels not experienced on this planet for millions of years. Planting more trees and reducing timber cuts world-wide will help restore the imbalance, and perhaps buy time as ways are found to reduce world greenhouse gas emissions.
