Erhm, what?
I meant "the cows" as a collective term towards farm cattle, not as a indignifying term towards humans.
@An
I don't really agree with your point on farm species going extinct.
Besides meat, farm cows, goats, sheep, and chicken all serve other purposes aswell, being milk, wool, and eggs, so I don't think that they would dissapear. The only farm species that might really go extinct, if we didn't keep it for meat, I think is the pig.
Plus, I believe that the exact same thing was said about horses, in the era that the ICE became a viable thing.
"What's gonna happen to horses if everybody starts using those fancy new petrol engines to pull their cars?"
Well, what turned out was going to happen to horses, is that people stopped seeing them as tools/machinery, and started keeping them as pets, and using them for sports.
Something similair may happen to farm animals.
But about bug meat. This may come faster than you think!
In scertain places in south America, (and undoubtedly a few other places) people are already eating bugs on a daily basis. And, besides how most of them aren't bad for your health at all, most western tourists that go there, and actually have the nerve to eat fried tarantula, or grasshopper pancakes will say that they actually taste really good!
And, not so long ago, I stumbled into a random market thingy, meant for dog owners, (In the Netherlands) and saw a brand of dog food that seemed to be entirely made from some sort of insect. So, who knows how long it'll take before we humans here in the NA, and Europe, find out that we can eat bugs too?
