Reply to comment by PastelFlamingo150 in ELI5: Why is it that when fertilizers make their way into waterways, all the oxygen disappears, killing the fish? by Psychological-Dog994

I’m not sure if there is some animal that can “fix” it, but I know one of the biggest problems is that the lack of oxygen kills fish. If there’s an abundance of food, the fish will reproduce at rates that the oxygen in the water can’t support. It’s a good idea though!
