Trees - The Natural Answer To Global Warming

by Jeff Miller

Are trees the natural answer to global warming? Research shows that trees are great for the environment! Through cleaning and cooling the air around them, they grow by absorbing carbon dioxide and give off oxygen that we need to breathe.

Plant Trees to Save Energy & Money Have you heard the phrase, "money doesn't grow on trees?' "Well, it can and it does," says Lin Diacont, President of the Virginia Green Industry Council, "besides beautifying our homes and communities, trees are natural air conditioners and energy savers! Simply by following a few basic tree-planting rules, you can save energy and money on utility bills." For example, an acre of young trees annually produces enough oxygen to keep 18 people alive and at the same time, absorbs the amount of carbon dioxide produced by driving a car 26,000 miles! Studies conducted by research universities have documented air-conditioning energy saving as much as 50 percent or more by shading the windows and walls of your home. For, tree leaves not only block the sun's rays but give off moisture that cools the air in a process called evapotranspiration. Trees similarly make efficient sound barriers from traffic and factories. Each 100 foot width of trees absorbs about 6-8 decibels of sound intensity. This reduction would be welcomed to residents along a busy highway, which can generate as much as 72 decibels. So, the next time you plant a tree for its aesthetic appeal, be aware that by following a few guidelines, you will not only beautify your yard but improve air quality, lower energy bills and reduce unwelcome noise.
