If you're debating between a live or fake Christmas tree, here's the green winner: live. Fake trees are manufactured overseas (translation: fuel costs) and are made from non-renewable, non-biodegradable materials. When thrown away, they clog our landfills. A live tree is usually grown on land unsuitable for farming anyway, but it still contributes oxygen to the atmosphere. Trees are also recyclable and most communities have such programs in place.
