The global fishing industry is massively unsustainable. Some estimates put the global decline in fish stock at 90%. The best counter arguments that other scientists can come up with is that a) they didn't reflect local figures (which also show a decline) and b) it's actually only 70% or whatever massively too high but still lower than 90% number they've come up with today. The point is that fish numbers are declining. Fast. When we say 90%, we're talking about 90% in the last 50 years. The way things are going, every commercially harvested marine species will have crashed by about 2050.
And that's just fish in general.
Bluefin tuna is as endangered as the white rhino, but it is still being hunted to extinction. If it was gorillas that were being eaten then thousands of people would be up in arms about it. But it's not. Fish are not cute, they're not seen as intelligent and they don't look like us. We can't see them, so we don't notice them declining. Out of sight, out of mind. And so it continues. Of course, the big companies aren't helping. Japan is alleged to have traded donor aid promises for votes to stop CITES from protecting tuna, and Mitsubishi is stockpiling frozen fish so that they can make money when the extinction of the species pushes prices up. All in all, things are not looking good.
Fish farming is not the answer people like to pretend it is. Farmed fish are fed on wild fish. It takes more fish to feed the farmed fish than what you get at the end of it.
What you can do:
- Find out more - knowledge is power
- Stop eating tuna
- boycott Mitsubishi
- Look for the Marine Stewardship Council (MSC) label on all fish products.
