Golbal Warming

I believe that is the human activity is part of Global Warming because we are harming the earth with all of the waste that we create. We are ruining the ozone with all the chemicals that we use. I think that we should just keeping trying to cut back on all the plastic and everything else that is harming the earth. Besides the people i do feel that the climate is changing some. If you look at everything that has happened in the past then you will see that the climate will eventually change how long will it take? well no one knows.....
