<span>1: global warming can harm animals and plants in the ecosystem (even ourselves). global warming is when you litter and throw trash on the ground, and also the more trash that is sent to the dump can cause global warming to get worse. Trash in the ocean can harm animals, they can eat it and get sick, or get it caught on them. It makes our earth become warmer and energy levels change. It can also hurt our atmosphere.
