Ok, maybe I came across incorrectly.

Obviously, I do care. I do care on the level of having strong regulation, having institutions and governments which regulate this, so that at the end as a customer when I walk into a store I don't need to Google whether a particular brand is fishing tuna in a particular way or not. I expect that the entire structure that exists for regulating and allowing these products to reach the shelves will prevent products which are made in an insustainable way. Maybe I'm a fool for expecting it to work this. But that was why I replied how I did - that I refuse to feel bad because I expect my government to prevent this in the first place. Just like I said elsewhere - I don't worry whether a phone I'm buying was made with child labour because I believe all governments involved in the production of the device enforce laws against child labour.

That doesn't mean that I don't care. But if I find out that phones made by kids or tuna fished to extinction is on store shelves I'll complain.....to the regulatory bodies. Not decide "well, I guess I'll never eat tuna ever again".
