While they're growing, real Christmas trees support life by absorbing carbon dioxide and other gases and emitting fresh oxygen. This helps prevent the earth-warming greenhouse effect. Every acre of Christmas trees grown produces the daily oxygen requirement for 18 people. The farms that grow Christmas trees stabilize soil, protect water supplies, and provide refuge for wildlife while creating scenic green belts. Often, Christmas trees are grown on soil that doesn't support other crops.
Artificial trees are a petroleum based product that consume vast resources during fabrication.
A burden to the environment, artificial trees aren't biodegradable and will remain in land- fills for centuries after disposal. The average life span of an artificial tree is only six years. Real Christmas trees, on the other hand, are easily reused and recycled. Christmas trees are biodegradable - the trunk and branches can be used as mulch for gardens, parks or in animal stalls. The mulch provides a protect barrier for the roots of other plants and vegetation while preventing weeds from growing.
