The US has nearly 7 acres of land for every man, woman, and child and yet the average lot size is only .2 acres. Since the average household size is 2.5 people, that’s about 0.08 acres used per person. Moreover, that figure ignores apartment, condo, and other multi-family buildings, so the actual land usage per person is quite a lot lower. Of course, we also need farms to support people, but the US produces much more food than it needs. And yes, the population is growing, but that growth is tapering off and anyway we could manipulate our immigration policies as well. At the end of the day, the US is a vast country, but this isn’t immediately obvious to people who have lived their whole lives in a dense urban environment.
Did you misspell "world" as "US" ? Or are you dishonestly using non-representative figures? The US has a much smaller proportion of the developed world's men, women and children than it does the land, and those men, women and children are extremely carbon-intensive.
