"30-50 percent of yield increases could be attributed to synthetic fertiliser inputs" So that's the theoretical drop in production if we can't buy fertiliser, however some farmers aren't even planting crops because of fuel costs and labour shortages for picking The UK imports like half of its vegetables and 80% of it's fruit, so fuel will impact on these areas too. The prices of these have gone up maybe 10-20% so far this year I think there will be enough food because poorer countries will still want to sell to us, but it's going to go up like another 30-50% To me this is manageable because my food bill is really low already, and I could eat turnips and potatoes all year long if I had to, it's going to suck for millennials though as they have never had to do without the current huge variety of foodstuffs. . If some niggers die from starvation then it would be totally worth it. South Africa is going to be a blood bath though
