one can threaten the environment by polluting because when u pollute it affects the air but people health not only that it affects our oceans and it can kill the animals. it also makes our air quality so bad by 2050 its gonna be so bad we will not be able to breathe. it also affects the ice where the polar bears are and right now its melting and so there wont be any place for the bears to lay or rest it will just be complete water
