Over pollution can contaminate animals habitat, food, and water source. I hope that's what you were asking for. I didn't really understand your question
The habitats of animals will be destroyed no matter what kind of pollution. They can br harmed by curtain objects in pollution for example sea polution with the fish and plastic. Also some anims may die and the ecosystem and/or foodchain will break down which creates a increase and decrease in animals. I could go on for hours. Just let me know exactly what you want to know and I will see if I know. Good luck.
