Concerning Fish (in general): Leonardo DiCaprio cares about our oceans- shouldn't you?

Wikipedia (labeled for reuse)

Leonardo DiCaprio is contributing to the campaign against overfishing by donating 2 million dollars, to combat it. I'm not saying that you need to donate 2 million dollars, no one is. But, what this should show you, is that the oceans do need our help. Even if you cannot support the cause monetarily, there are other things you can do. Namely NOT eating fish- alright that's a little rash,  but please, stay away from threatened species, such as Bluefin tuna. I will post resources to find out which fish are sustainable in a few days.

Don't eat bluefin tuna! Alright, my fish slogan still needs work...
