One of the most important things that trees give people is oxygen to breathe. Trees also give shade, house animals and muffle noise.
Trees also clean the air and filter airborne pollutants. Trees can reduce utility bills if they are placed in the right spot by providing shade on a house. Trees that are fruit bearing also provide food for animals and humans. Trees also provide shade in parking lots for cars. By doing this, they reduce ozone emissions from vehicles. Trees can also block out noise pollution because they will absorb sound, and they also help provide hundreds of different animals a habitat to live in.
