Just thought I'd let you tuna eaters know. (I've got nothing against you)
In my Greenpeace mag today I read that John West and Princes brands, which together make up 60% of the market, are the worst at ensuring the fish they sell is caught using sustainable methods.
Here is a list of the best to the worst;
Asda, Tesco, CoOp, Marks and Spencer, Sainsbury's, Morrisons, Princes then John West.
So now you can choose wisely.
