Question: Do fish help improve our enviroment in anyway or not?

Yep they can actually help clean it up, by nibbling on algae that might over-grow if they don’t! They’re also a very important part of the food chain, so we shouldn’t over-fish them. There’s lots of work going into how they can help control nutrients and oxygen in the oceans… but we do know they’re important for a healthy environment!
