When the world hit 10 billion, you will have a legit problem. Food. Where will the food come from?
Pollution cleanup will not help with the food supply.
Because of all these, i am beginning to believe 500million is all the earth need. Just like what was written on the Stone in Georgia.
If you include seasteading, along with pollution clean-up, we are looking at a world that can handle 100 billion.
