(The 10-20% is a guess, based on one large plant and some other plants, without hard data. If anyone has real data, step right up.)
I was in Richmond, Virginia 10 days ago, and people were saying there was no meat in grocery stores, so they went to Texas Roadhouse in order to be able to eat non-vegitarian, because Texas Roadhouse still had steaks.
There's locust swarms in Africa, and it's potentially heading towards China. I expect there to be widespread food shortages in the coming weeks/months. I'm not sure about how life will be here in the US. We're rich, we're a net food exporter, etc. as long as the processing and other supply chain parts keep mostly working I think we'll be okay-ish. You might not get the exact product you want, but you probably won't face starvation. But in many poor countries in Africa and Asia, I think it's about to get really, really bad.
