Not to the levels you can expect if it is all industrialized. You are correct though. A strawberry from 50 years ago tastes a million times better than the monstrosities we buy today as a quick example.

Which I think is almost worse... think about concentration/extermination camps (which I think our animal industry is basically)

And it's perfectly healthy to be vegan (maybe even more healthy at this point when done right, than meat consumption).

My main reason though for that is less moral than just wanting to be less wasteful, i.e. meat is just inefficient. I predict that we at some point will move past meat consumption, it's just not necessary, even when considering taste...

Did you mean to say plants instead of animals, or...?

The smell of cut grass is the grass warning other grass that doom is upon them. Plants communicate in ways we can't understand in the same way as they don't make noise. They don't like being harvested anymore than an animal does.
