Well because not only does it improve our environment but it is also good for your health. Plants breath in what we breathe out, carbon dioxide. Plants give off oxygen which we breath in. Not only do they suck our carbon dioxide in so we don't have to breathe that but they give off the oxygen to improve our breathing and the health of our lungs is much better then not having a plant. When you think about it, having many plants is also a good decoration inside or outside your home.

3) It can be a good decoration inside or outside your home.
