One big reason we haven't had a global food crisis is because of GMO food. Norman Borlaug's (https://en.wikipedia.org/wiki/Norman_Borlaug#Expansion_to_So...) work in particular comes to mind as being almost single-handedly responsible for staving off massive famines. Part of that work involved selective breeding to produce a strain of wheat that would produce more output in the same acreage.
