* Wealthy nations accused of depriving poorer ones of nutrient-rich food and wasting mackerel, sardine and anchovy stocks -- to feed farmed salmon.*

I don't think there is anything wrong in principle in farming salmon, but we who are wealthier must not starve the poor.

At the same time, every country has an obligation to stabilize its population. If we don't end population growth, it will reduce everyone to poverty. Now that we are hitting global resource limits, no people should imagine that they can have population growth without taking from other people. Humanity must back off from these limits, and the only human way is by a lot fewer births.
