Do you think the world can cope with 10 billion people?Watch
Depends how long we're talking, considering that it's constantly growing then it wont be too long before we start running out of essentials and we have to restrict ourselves. Fuel will begin to become a luxury then illegal to use unless its in industry, then i have no idea
Yeah. I mean for the long term. (Your probably going to ask how long is long term?)
Without some extreme decisions i don't think so. To power stuff with simply burning wood to power generators you need a lot of space which i dont think we have for trees. Instead the space is used for houses and farms.
We would have to do something like Japan and restrict the amount of children u can have. What would be slightly (not too much for obvs reasons) funny is if the government dont tell us about the cure to some major virus, gets half the population killed then cures everyone
