1. The United States and Canada could try to use less paper in order to not have to cut down so many trees and destroy wildlife. We also need to limit the amount of fish we catch per amount of time because we need to give them time to reproduce or they could die out. Also do the same with hunting other animals.

It forms when cars, power plants, and factories release too much chemical emission like sulfur dioxide and nitrogen oxide, it corrodes stone and metal buildings, damages crops, and pollutes soil. The same chemicals are to blame for smog which make the air qualityy very poor and is dangerous for people to breathe and may cause respitory problems. Water pollution occurs when sewage and industrial wastes are dumped into oceans lakes and rivers, this is always bad because we use water for everything and it puts harmful chemicals into it.
