The shrimping industry itself is an environmental scourge much older than the oil spill. Farming is responsible for habitat destruction, while trawling for wild shrimp is harmful to the oceanic environment. So which is the lesser of the two evils?
Ever hear of a "dead zone"? I don't mean the book by Stephen King. I'm referring a typically large swath of ocean that is so depleted of oxygen that most aquatic life caught in one either suffocate or escape the region.
