Polution is basically trash, so when this trash starts to break down it turns into even smaller pieces, and these pieces can get into fish air ways and block them, or the pieces can be ingested because the fish thought it was food. This then causes issues with the fish because of the chemicals inside the pieces that can cause the fish to die. The pollution can relaese chemicals into the water, and since the chemicals are in the water where the fish are eating, swiming, and breathing it can cause issues resulting in the fish dying.
