Answer:
Humans do both
Step-by-step explanation:
Harm- Humans harm the environment, think about all the trees getting constantly cut down because we need paper. Also climate change, we have caused the earth to become hotter than it has been. This is because of the fact that we use gas powered cars, and factories and more on that.
Help- We also care about the environment, or at least some of us. Some of us plant, garden and try to help animals in Africa or in South America. We also help the environment by advocating for it. Telling everyone whats going on and trying to get others to join us in making the world a better place.
