Of the almost 247 billion trees in America that measure more than an inch in diameter, one Coast Redwood tree in California measures 369 feet tall and is more than 2000 years old. Trees provide food, shade, wood for constructing buildings, cooking and heating fuel and fibers for making paper.
Trees talk to each other. When insects invade a tree, its leaves can produce a chemical to discourage the invaders and warn the neighboring trees. The other trees in the area receive the warning and start producing the same chemical to protect themselves. No other organisms on Earth live as long as trees.
