Dependence on food imports? The US is a large net food exporter. And will remain so for a long time. Especially in wheat, corn and soy beans. Harvesting grains is incredibly labour efficient. The labour crisis is mostly in fruits and vegetables which are very labor intensive. Even if soy and grain yields would be unexpectedly badly impacted by climate change it will first impact the exports and lastly animal feed and agro ethanol. The yields would have to be unrealistically devastated for it to lead to shortages in human food like bread. So at worst we are looking at a shortage of meat, fruits and vegetables but we are extremely far away from any situation involving starvation. This also includes Canada, the EU and Australia. And it’s not all vegetables either. Potatoes, carrots, peas and onions are machine harvested and won’t get affected by a farm labour crisis and will continue to be available. No one is gonna starve for having to substitute broccoli and asparagus with carrots and peas. No one is going to starve when fruits gets expensive either, they are healthy but you can live without them.
It’s the part of the third world which currently relies on western food exports that will have food insecurity in a worsening climate crisis. The west is at worst facing a more boring and monotone diet.




Soy fixes nitrogen and doesn’t affect the rest of the nutrients. Without soy in the crop rotation you have to simply buy more nitrogen fertilizer for the subsequent crop, which will make it more expensive to grow. Soy is good but it’s not a looming disaster without it. The EU barely grows soy and is doing fine. And regarding dust bowl. Those areas of the US have already switched from plowing to no-till decades ago. Another dust bowl is unlikely even with drought because of it.
