This Friday is Arbor Day, a day when schools, communities and homeowners plant trees to help make the world a better place. Trees help slow climate change by removing carbon dioxide from the air. A single tree can absorb a ton (2000 pounds) of carbon dioxide over its lifetime.
Trees help cool the planet in other ways, too. Neighborhoods with trees that shade streets and sidewalks can be 6 to 10 degrees cooler than neighborhoods without trees. That means people don’t need to use energy to run air conditioners. And shaded parking lots keep automobiles cooler, reducing emissions from fuel tanks and engines. Trees also block cold winter winds, attract birds and wildlife, purify our air, prevent soil erosion, clean our water, and add beauty to our homes and communities.
