I can't believe in let's say 200 years from now humans will still consume animals - if our species survives that is. I'm sure this will be looked upon as very barbaric to breed real animals and eat them.

[Eisenstein]

If we survive 200 years from now we will either not really know what happened during this time because most people will be illiterate or we will be growing food by using the vast amounts of almost free energy we have figured out how to produce. I don't really see any other situations happening.

Is it barbaric when coyotes kill and eat a deer (often while still alive)? or when a lion eats an antelope?

[esafak]

No, because the argument only applies to animals with moral faculties, and the luxury of choosing what to eat.
