The Fish Fallacy Fish was the hardest thing for me to give up. Because it does taste good and it does seem good for you. But the more you look at the fishing industry, the more you see how human impact on the oceans has been devastating, and the more you see that eating the suckers doesn't help us much, either. From the poisoning of shallow waters to the drift-netting of the oceans, the impact on most coastal ecosystems is already severe. Almost all commercial fish catches are now in decline or bankrupt.
Fish is an extremely concentrated source of protein, cholesterol, and heavy metals.
Government inspection of fish is virtually nonexistent. The smaller the fish, the more likely you are to eat the intestines and fecal material along with the animal. The bigger fish eat the smaller fish and accumulate all the metals. There is just nothing worth getting from fish, unless you have no other source of calories. I love sushi as much as anyone, yet I am doing just fine without it.
