We all know trees are good for us– but why. An average size tree produces enough oxygen in one year to keep a family of four breathing. Three trees planted in the right place around buildings can cut air-conditioning costs up to 50 percent. By planting 20 million trees, the Earth and its people will be provided
with 260 million more tons of oxygen. Those same 20 million trees will
remove 10 million tons of CO2.
Plant a tree, save a life!
