In an increasingly crowded world, will we still be able to find respite from one another?
Sometimes it’s difficult to fathom that the world could actually become even more crowded than it is today – especially when elbowing through a teeming Delhi market, hustling across a frenetic Tokyo street crossing or sharing breathing space with sweaty strangers crammed into a London Tube train. Yet our claustrophobia-inducing numbers are only set to grow. While it is impossible to precisely predict population levels for the coming decades, researchers are certain of one thing: the world is going to become an increasingly crowded place. New estimates issued by the United Nations in July predict that, by 2030, our current 7.3 billion will have increased to 8.4 billion. That figure will rise to 9.7 billion by 2050, and to a mind-boggling 11.2 billion by 2100.
