Martin Empson unpicks the arguments of those who claim that population growth is to blame for the climate crisis.
At some point between October 2011 and March 2012 the world’s population surpassed 7 billion people. Whenever such a milestone is passed there is a rash of alarmist articles in the media warning of the dangers of uncontrolled population growth. In the years since 2012 the total has increased by a further 700 million people, which for some activists, politicians, demographers and media commentators only fuels the panic. As a result, you don’t have to campaign around environmental issues for long before someone will tell you that the problem is “too many people”.
