Sometimes I think humans are a blight on the planet

Study: All Commercial Seafood Species May Collapse by 2048, eliminating a major source of our food, but also disrupting the biodiversity of the planet and creating algae blooms, oxygen depletion, and ocean flooding. (I'm not sure how that last ties in, to be honest.) But the idea is certainly disturbing. The good news is conservation could help avert it. The question is whether countries that are heavy fishers will agree to it. Plus, you can't just close fisheries right and left--it would eliminate livelihoods and be politically unpopular. But there might be ways to limit the catches or protect certain endangered areas.
