Think about this. Those two statements are not mutually exclusive.

Think about what? Your sentence ends right there.

So billions more people are able to survive somehow now...but our "health" has gone down?

There is the health of the human species...which has gone up undeniably, evidenced by the billions more people being fed...and then there is the health of the individual human.

So you were referring to the health of an individual when discussing agriculture's impact? Sample size seems kinda small. Also...seems that most of us wouldn't be around for that discussion as the non-agricultural food supply would not allow us to be born.
