Stop Cutting Down Trees, Every year, 34 million acres of forests are cut down. Timber harvesting in the tropics alone contributes 1.4 billion metric tons of carbon to the atmosphere.
And when purchasing wood products, such as furniture or flooring, buy used goods or, failing that, wood certified to have been sustainably harvested. The Amazon and other forests are not just the lungs of the earth, they may also be humanity's best short-term hope for limiting climate change.
