You know how it works - the big fish eat the smaller fish and the smaller fish eat the little fish and the little fish eat the really mini fish ... and so on. Uh-uh. Not any more.
Here's a post that assumes that you, as a surfer, give a damn and feel part of the ocean, land and air system we call Earth. It's a very pretty graphic put out by the Guardian newspaper using data from Dr. Villy Christensen of the University of British Columbia, one of the foremost centres of worldwide fisheries research.
And, ugh, it's pretty graphic.
Below that is another info graphic showing which fish are OK to eat.
I could say, 'Enjoy!'
But that would be inappropriate, so how about, 'don't buy tuna!' or 'quit eating fucking sushi!'
You get the jist.
What can I do?
Here's a chunk from a website called overfishing.org - kind of a guide to guides in different countries:
"Eating with a (clear) conscience A number of Non Governmental Organisations (NGOs) maintain seafood guides / lists on fish to eat and to avoid. Aimed at consumers these lists are usually based on a simple colour system with green being good and red being bad. Not all list are of the same quality and not all NGOs follow the same methodology. In general these list do provide a good and easy buyers or consumers guide overview. Print a list on a small credit card sized piece of paper, stick it in you wallet, and always carry your environmentally friendly fish list with you! This overview is not as comprehensive as it can be and contributions, especially for new countries, are welcomed!
