On September 8th 2009 Dennis Decoteau from Penn State's Department of Horticulture did an experiment showing that houseplants in the house can help the ozone and the air stay clean. All over the world people need houseplants and if they do, we can save the environment. The ozone layer protects us from harmful UV (Ultra Violet) rays and if we keep it clean, we can have a safer, cleaner Earth. For Decoteau's experiment, he placed a snake plant, a spider plant and a golden pothos into a greenhouse chamber to tell weather it helps the ozone layer or not. The experiment showed that some plants help the ozone better than others. Houseplants also help people become happier. 82% of the participants that have plants at work or at home feel happier or "content. My opinion on this subject is that I think that we should all have houseplants in our house because it will help the whole world!
