watching it now.
I'm coming to the opinion that all the world's ills are coming from there being too many of us - I mean the social/geopolitical problems too.
Projections apparently reckon that we're headed for a world population of 10.3 billion, we're currently at 8.2.
The challenge is coping with the extra 2 million possibly with all these points of no return flying by, without descending into all-out war because of all the crises that come with the loss of liveable places.
