If you use an artificial Christmas tree, you can fold it up and store it for next year. If you have purchased a live tree including the root ball and live in a warm environment, you can plant it in your yard and enjoy it for years to come. A lot of communities have some sort of recycling for cut Christmas trees. Some of them have curbside pickup to recycle the trees. Some communities use old trees to shred and cover trails and pathways through parks. This helps to reduce and repair the damage created during hikes. Some communities turn old trees into mulch and then provide it to the public for free. Think about getting a fresh start in the New Year and reduce your holiday effect on the environment.
