While they are growing, Christmas trees support life by absorbing carbon dioxide and other gases while giving off fresh oxygen. Every acre of Christmas trees planted gives off enough oxygen to meet the needs of 18 people. Today in America there are enough Christmas trees planted that 18 million people a day are supplied with oxygen. Also, the farms that grow Christmas trees stabilize soil, protect water supplies, and provide a refuge for wildlife while creating a nice scenic view. Often, Christmas trees are grown on soil that will not support any other crops. And when one Christmas tree is cut down, one or two are replanted in its place.
 

Artificial trees are made from oil-based products that use up our natural resources. They are also not recyclable and will remain in land-fills for centuries after disposal.
 

Real Christmas trees, on the other hand, are recyclable. The branches and trunk are biodegradable and can be made into mulch for the garden. A Christmas tree placed in the back yard will make a nice bird feeder and the birds can also use the trees branches for shelter during the winter winds. Large quantities of trees make effective barriers on beaches to prevent soil erosion. Sunk into ponds, the trees will also make an excellent refuge and feeding area for fish.
