The effect that plants have on people and animals play a big part in today's world. Plants and trees that grow upon the earth are used and needed in many ways. They provide us with many things that our bodies need to survive. Plants and trees work together with people to give off these important things needed to live. The greatest thing that plants give us is oxygen. As we all know, oxygen is the main thing we need to live. Without plants and trees we would go extinct and without us, plants would not exist. As plants give us what we need, we give them what they need. We exchange carbondyoxide as they give us oxygen. Although they're a lot of things plants need , we are the most important.
