This Malthusian notion that the world is overpopulated is such an old idea and it keeps being debunked over and over again. https://www.scientificamerican.com/article/why-malthus-is-still-wrong/; https://www.forbes.com/sites/larahoffmans/2011/10/31/7-billion-reasons-malthus-was-wrong/.
There really is no danger of overpopulation. If there was, then the only logical answer to this is to depopulate the planet. You say yourself that "we are failed to control the population". What does this lead to?
Eugenics. Abortion. Mass sterilizations.
Is that what you want?
