Otherwise the more food and water an area can provide in a perfect scenario the greater the end suffering will be when some inevitable problems occurs and the now larger population's demand's exceed what the land can supply : either due to war, drought/crop-failure or just the feedback delay between successfully increasing child survival rate and there being a baby-boomers population spike in high-consumption adults.
Maybe Education can help with that, but even in '1st-world' countries we still seem to have a problem with some people having many more children than they have the means to support themselves (currently a bit of a hot political topic in the UK with the government wanting to try and reduce the cost of supporting people on 'benefits')
