Impact of society on environment

          Here are some example of the impact wich is made by people or society to the environment. The first one on my list is cutting trees. Trees are important for all living things, but things that are made of wood is also important for people. So what we can do is don't cut trees for an unnecessary purpose. Next up is air pollution, as human, we polluted the air by giving out carbon dioxide from car vehicle engine, factory and burning stuff.Last on our list is oil spilt. An oil spilt is the released of liquid petroleum hydrocarbon into the environment. This affects the animal life that lives in water which can cause death. That's it for the blog!!!!!!!!
