It was once believed that the oceans and seas were so immense we could never use up all the resources they had to offer. However, we are finding out the hard way that this just isn't the case.

Many commercially harvested species are in danger. In Europe, it is estimated that approximately 90 per cent of all fish stocks are overexploited, and populations of haddock, salmon, cod and halibut are so badly damaged that stocks may never recover.

 Bluefin Tuna is a species facing a similar fate. Bluefin is a species valued by sushi loving countries like Japan and is fished heavily in places like the Mediterranean and Atlantic. Populations have plummeted by an estimated 80 per cent since 1970. Still, this was not enough to convince members of the United Nations to place the fish on the CITES list, which could implement strict regulations and international trade restrictions. The proposal was voted out  in large part due to Japanese lobbying, and support from other fishing nations who fear more CITES additions if the proposal were to have passed. In addition, some sources now estimate that as much as one-fifth of the total global fish catch annually is illegal or unregulated, making sustainable management almost impossible.
