It isn't morally wrong, it goes against your morals maybe, but that doesn't make it wrong. We are allowed to disagree and you are free to choose the diet you prefer, as are the rest of us.

it takes MUCH more plants to feed animals to then feed humans.

most of the plants fed to animals are parts of plants we can't or won't eat. a great example is soy: we run over 4/5 of the global crop through an oil press and extract what we want, and feed the leftover plant matter to animals. no more plants are harmed in this process, and we conserve resources by getting food back from the animals.

And yes, it’s ok to kill plants because they do not feel pain

you can't prove this

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.
