Planet

"Every year, the planet loses a patch of forest about the size of
Louisiana- a staggering statistic, given that half of Earth's original
cover has already been burned, cleared, or cut down. Trees remove harmful
CO2 from the atmosphere and are nature's best defense against climate
change, which is why the United Nations named 2011 the International
Year of Forests. You can help by paying bills online, unsubscribing
from junk mail, and looking for the Stewardship Council logo when buying
paper or wood. You can also take "think before you print" one step
further by saving your computer files in a format that can't be printed.
