The same usual overpopulation (myth) BS again and again and again
. At first our world is not a closed environment, therefore there are no theoretical population cap. Secondly more than 50% of the population living in cities what makes those places overcrowded, but overcrowding not equal to overpopulation. Thirdly, currently we are producing food and drinking water for more than 10 billion ppl, so there are no food and water scarcity issue, the crap what you see in many places is happening only because of the unequal distribution and extensive wasting.
Please do not believe in all the crap what the MSM trying to push to us.
