That's only true if fertility rates stay above the replacement fertility rates. As nations become more developed, fertility rates tend to fall. In the EU-28 the fertility rate was 1.58
children per woman in 2015, well below the replacement rate of 2 [1]. India's fell from 5.9 in 1960 to 2.4 in 2015 [2].

Your Malthusian view is outdated. We can easily feed and shelter the current population (and projected peak population) for the foreseeable future.
