This is all bad (about the negative points). This all happens while in many developed countries families often either have 1 child or not at all. Now it is inconspicuous, but imagine what will happen in 50 years. The population is going down a lot. Therefore it is not necessary to go to extremes. The problem is not overpopulation, but how it is organized. But I agree that on one territory there should be such a number of people who will be comfortable. There should be so much land that every person can be full when some kind of agro culture is grown on these lands
Yes if there's enough land people can cultivate many crops by cultivating Because the population is increasing at the speed of food production isn't increasing. People consider the population because the biggest problem which may be a major obstacle for developing countries when the population is above required that's why we all got to increase the quantity of cultivable land.
