@Sporkasia - Environmentalist are always complaining about all of the ways people are harming the world, but the world is still turning. Some species of animals are going to go extinct regardless of what the reason. Isn't that the basis of Darwin's Survival of the Fittest theory?
I haven't counted, but I bet there are a lot more fish swimming around the ocean than fishermen will ever scoop up with their nets. You want proof of the ability of ocean habitats to adapt and survive? Then do a little research and read about how the fish and plants in the ocean have recovered after major oil spills.
