However, there is a trap in this. Right now, there are cows and pigs wherever there are humans.
Fast forward 200 years when we can grow our own meat in the lab. Who's going to keep around livestock? For what reason?
Pigs and cows would exist in a wild state in a small fraction of their former "territory." If at all.
The people who want to eat actual animals.
>For what reason?
I wouldn't be so quick to assume that cloning muscle cells is the same as meat and it will replace all animal products. What about (almost) raw pig skin [1]? It's delicious and people in this post say skin isn't so easily synthesized.
Pasteurization was invented a long time ago yet people still make natural milk products. If I'm not mistaken these are illegal in the USA.
Why would that be a problem?
