I don't think you can say 90% because that's based on your opinion not scientific fact.

If you're considering 2017, there's multitudes of variables that are involved in that consideration, but you only focus on one. You don't address the reasons why that may be, which could very well be connected with conditioning via other individuals or society. So the root cause of your argument isn't because a human wouldn't naturally do it. It may be because we were never taught to. Or we are now so conditioned to "2017" that we can't individually function as organisms of survival anymore, at least not when it comes to mother nature.

Also, you're only arguing with a selective sample size. The "modern" world. But there are still many small hunter-gatherer tribes in existence today, their communities hunt and eat meat. And in those populations, your argument isn't true.
