Answer:
I think the biggest threat to the environment and how much pollution we have and how much is in the air, because obviously we breathe oxygen,and that's what air is. when someone throws water on the street I feel like they're just causing a bigger problem for the environment,because it just adds more pollution to the Earth. I told someone not to litter and they're just picked up and threw it away they didn't really think it was a big deal. some of the appositive examples I know our recycling, reusing, and using less plastic materials.
