Is the world running out of space?

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.

Yet even today, it’s difficult enough to get away from one another. Drive a few hours outside of New York City or San Francisco, into the Catskill Mountains or Point Reyes National Seashore, and you’ll find crowds of city-dwellers clogging trails and beaches. Even more remote and supposedly idyllic spaces are feeling the crush, too. Backcountry permits for the Grand Tetons in Wyoming sell out months in advance, while Arches National park in Utah had to shut down for several hours last May due to a traffic gridlock.
