even the oceans aren't safe from our commerce

it looks bleak,with 'pronouncements by scientists about the imminent extinction of bluefin tuna and the possible emptying of oceans by mid-century'... but 'we must continue to call for a ban on fishing for bluefin and other endangered species and push for better regulation and enforcement when it comes to global fisheries. As consumers, we should also increase our awareness about seafood, and avoid eating fish that are in danger. If people in countries like Japan and China were to get serious about sustainable seafood, that would help as well. It would also be great if we could shift our thinking about economics to include the value of conservation and the services that ecosystems and plants and animals provide for us.'
