Atlanta

Environment

For a major urban area, Atlanta has an unusual degree of tree cover, and the city works hard to keep it that way. A government permit is required to cut down a tree, and all trees that are removed must be replaced by a variety of shade trees. Trees Atlanta, a nonprofit organization dedicated to tree conservation, planted more than 12,000 trees in the 1990s.
