On one hand, I agree about eating meat. I'm not willing to give it up, and I would feel much better about it if nothing were killed in its production. On the other hand, I suspect that lab-grown meat might be an existential threat to a number of animal species, if it becomes inexpensive enough to make farming or ranching unprofitable.

For example, in recent decades, we saw the American Bison rescued from the brink of extinction when people figured out how to ranch it profitably, and now the species is thriving. If you could buy lab-grown Bison meat for cheaper, what would happen to all the Bison on all the ranches that suddenly couldn't afford to maintain their herds?

Although it's counter-intuitive, if there's really a market for meat from things like giraffes or elephants, I wonder if the best thing for the species might be to follow the example of the American Bison and find ways to farm them and sell them legally.
