Honestly I don’t have a problem with their being a meat shortage. IMO it’s a good thing. I’m investing financially in meat alternatives like Beyond Meat products.
A meat shortage would be a catastrophe. Not everybody can afford the finest of fresh fruits and vegetables. And the food supply certainly can't contain a major shortage.
I'm not being drastic but vegans don't want omnivores trying to get full off their supply. It would imbalance the food supply and drive up prices all over the world. As the demand for grain, fresh/frozen/canned produce, soy, legumes will be great. It really isn't enough to go around poor people already rely heavily on these staples.
