There are several things we have plants for. 1. Oxygen- Plants convert our waste Carbon Dioxide into oxygen. 2. Food- Humans eat plants and so do the animals we ourselves feed on. 3. Housing- Some people live in trees. 4. Materials- Wood is a key material and very versatile. 5. Beauty- They're nice to look at. And I'm sure that there are several more.
