Research it but there was multimillion dollar problem in Los Angeles and the ocean. Farmers used deadly pesticides in their fields. The pesticides washed through the soil and into the creeks and river and went out into the ocean. The fish swam in the water and absorbed the pesticides. The fish were deadly for people to eat. Eagles swooped down and grabbed the fish and ate the fish for years.
Eventually the eagles bodies absorbed the pesticide. Then when the eagles laid eggs the eggs were paper thin and crushed when the eagles sat on them in the nest or the eaglets inside didn't develop.
So like a domino effect killed bugs in the fields, decimated the fish population and nearly wiped out all the eagles. That pesticide is now illegal. All thanks to industry not caring what they put into the environment.
There are lots of other things but that one I'm well aware of.

I agree with your point of careless human attitude because it happens because of human behavior and carelessness only.
You have not illustrated any connection with "industrialization".
