How has Humanity Abused the Environment?

How has humanity abused the environment? 

Humanity has abused the environment in many ways including pollution, over population, releasing carbon dioxide into the atmosphere, and putting many harmful chemicals into the earth.

Pollution is a huge problem in America and all over the world. Although it is against the law in almost, if not every country, people still disrespect that law and litter anyway. This only creates an unhealthy and ugly earth that and if people continue to litter and pollute, it will eventually become filled with garbage and pollution. Also, humans are putting carbon dioxide into the atmosphere which it burning holes in it, this contributes to global warming which will eventually also become a major problem and a threat for humanity.

Humans are also over populating the planet. This is extremely hard to prevent because unless you are communist, you tell people how many children they can have. And I am not telling people that they shouldn't have children but humanity as a whole needs to come up with a solution to prevent the world from becoming over populated. And also, the more people in the world the more garbage and pollution and chances to make the earth even more messed up.

We also have eliminated a lot of trees and wildlife on the planet. A ton of animals have become extinct because of us. Everything such as the plants and animals have grown and adapted on this earth for a reason or a purpose and as the animals, trees and plants die because of us, we are only taking away something that helps the earth in some way.

I think that what people don't understand about all of this is that the earth can actually over populate, or be taken over by global warming or in other world "die". I even find it kind of hard to wrap my head around the fact that the earth could die if we don't help it and stop all of the destructive things that we are doing.
