Isaac Asimov wrote a book called, 'The Caves of Steel' in 1955 which assumed that our population would be 8 billion in a thousand years time. Like much of what he wrote it was a warning.
He is known and respected world-wide. David Attenborough shares this opinion with you/I/us; and, has spoken about this particular problem of irresponsible, uncontrolled, world over-breeding . . . but, it is not - regrettably - repeated often enough .

David Attenborough | "The source of all our problems = POPULATION GROWTH"
(Apologies for BOLD. Having problems with formatting and spelling today ).
In his, 'A Choice of Catastrophe's', he cite not controlling our population as our biggest danger (1980).
We have known of this problem for over 220 years and it has become a major problem in the last 50.
It won't destroy us, merely make life for most of us far less good.
As I said, I will be glad to be out of it.
