Arbor Day Foundation
- Trees
For many people, trees mean natural beauty, cool shade, a bird's song, and brightly colored leaves in autumn. Trees clear the air, conserve topsoil, and protect our water supplies. They cool our neighborhoods and shelter our homes so we use less energy. Forests provide habitat for millions of species that are integral parts of the ecosystems of our planet. Trees provide lasting memories. Of cool shade on a hot summer day, the big old tree that grew near your home. Trees, in short, are priceless.
