Unethical and immoral business idea
So y'know how some lizards can re grow limbs? Here's my idea. Get thousands of them, put em in farms. Automated tail choppers. Feed them a little, give it a couple weeks. Wait for it to grow back. Chop again. Very slow. And a lizards tail isn't that big, I know. BUT. If you have THOUSANDS of them, that's something. A thousand lizard tails is pretty solid. You could make stew or something. Or cube them and make like lizard spam blocks.
The largest lizard I could find that actually regrows it's tail is ~22 inches long. Probably not very accurate but I'm gonna go out on a limb and say that it's tail is about like 5 inches or so. And it's pretty thick. Not bad
