Health issues are minor side-effects compared to extinction of tuna.

A few years ago I quit buying tuna altogether, fresh or canned, and I wish
you all would do the same. I've made sushi at home regulairily about 20
years now and I really would not like to serve my guests 'the last piece
of tuna'.
