Less meat consumption should lead to more production and decrease in price of of other types food. Also despite all the suffering in the world people still care very much about the wellbeign of dogs and cats. If anything with inflation and more and more wars around the globe the world needs cheaper food now more than ever.
The inputs into meat today are things like soy and feed corn, which aren't particularly good for people. It's not quite as easy as just not eating meat. Many of the farms need to switch to other crops that are healthy which requires different machines, more labor, or other factors. You probably aren't going to see too much drop in other food prices since much of the cost of foods (especially corn and soy related) is in the processing and distribution, not in the actual growing. Then you need to convince people they want to eat whatever the new product is. You could give people something made from scraps similar to dog food, but that's not going to go over well for a bunch of reasons.
> the world needs cheaper food now more than ever.
We are getting there. The price of food has crashed pretty hard over the last couple of years, and we're already back to 2019 levels, with little sign of that trend stopping. Barring some major shift, food will be cheaper than ever by next year.
It may not actually be cheaper food that you need, but rather cheaper retail workers. While food has crashed, the price of food in the grocery store still seems to be climbing.
