Why are farmed fish bad for the environment?

Farmed fish also breed with wild fish, which contaminates non-farmed sources of fish and leads to decreased genetic pools. Farmed fish also out-compete wild fish in some cases, leading to population decline of healthy, natural fish. There’s a less obvious problem to do with the relationship between fish and soy.
