changes in food supply due to climate change

Drought in the US has wiped out 45% of the maize and 35% of the soya bean crop in the worst harvest since 1988. Pig farmers are using more anchovies because maize is now too expensive. Salmon farmers are using more anchovies because warmer seas mean the salmon are growing faster. Anchovies are increasing in price because pig and salmon farmers want more of them, but also because of storms, Peruvian government quotas, and organic farmers wanting more fish meal as fertiliser. Anchovies should not be used for animal feed, let alone fertiliser; it is a complete waste.

Salmon prices have dropped dramatically. Fish oil, used as a nutritional supplement, will increase in price. Burgers will increase in price. Mackerel are being overfished because warmer waters mean that they're moving further north into Icelandic and Faroese waters. All this I have learned from this Guardian article Anchovy price leap causes food industry chain reaction. Elsewhere I have learned that the price of lobsters has plummeted because of warmer seas.
