so you are unable to make the connection between the green revolution and the starvation that did not occur because of it.
That unfettered population growth will result at some point in a food shortage that some scientist like him will not be able to fix.China's premier told President Bush what keeps him up at night was the thought that of all Chinese coming from the county side going to the city's to demand food and jobs.but somehow more Chinese would make this problem better?

Oh, you're switching your argument. Okay.
(1) "Technology might not keep up." Again, what happened in the US? Stagnant/significantly decreased growth rates in population. Didn't need drastic measures for a problem which resolved itself. (Hell, the government may worsen the problem by subsidizing the production of children--by offering tax credits per child).
(2) "Rural emigration to the cities in China because Bush worried about it." And what do the immigrants offer in exchange? If it's voluntary trade, then they offer something useful in exchange for something useful. If there's involuntary exchange, then they'll crowd the cities demanding 'free' food and 'free' jobs. Obviously, we can point out the culprit in the latter scenario (governments). So, if your scenario of people running to cities demanding 'free' food and 'free' jobs holds true, then we should blame any government responsible for creating that incentive. If there are people running to cities who offer useful services in exchange for goods, then it's not a problem in general.
You could say the same of industrialization (i.e. the migration of rural individuals to the cities) of any nation at any point in time, but we get different outcomes, and each country faces different technological advances and institutions (e.g. property rights regime).
What have we seen with "First World Countries"? Stagnant/declining population growth rates (especially if we exclude foreign immigrants).
What have we seen with 2nd world countries? High rates of population growth rates (but they die quicker).
How about the 3rd world countries? Highest rates of population growth (but they die quickest).
(in general).
So, how do these differences matter? Do higher growth rates in poorer countries offset themselves due to the lower life expectancies and higher mortality rates?
(3) Green revolution isn't responsible for as much as you claim. That's why I don't "make the connection between the green revolution and the starvation that did not occur because of it." Sure, rising productivity of particular staples was great and all, but it's not what got people out of the Malthusian trap--if it ever existed.
