Having travelled extensively by air. I can say what I have seen from above.
When I flew the entire length of the USA it looked like over 85% of the land was empty.
When you fly over the UK it is the same.
Thailand also.
And many other countries. It would seem over populated cities are the real problem. To me at least.

I once covered on steemit the aging European population and decreasing population along with countries like Japan.

But and a big but, those in power positions no matter what they are, the wealthy, the so called elite, they all live in a different world to you and I and they despise us.

I would hazard a guess the world population is much lower than stated.
