Pesticides

I have been learning a lot about pesticides. Pesticides are chemicals that people use to kill annoying animals and plants. They can be helpful, when they are used carefully. They can get rid of insects and other creatures that cause people to get sick. However, often people do not use pesticides carefully. Sometimes they use too much, and sometimes they spray the pesticides places where they should not be. When this happens, the pesticides can damage nature, and they can make people sick. -Mr. Zahnd
