Conservationists tend to spend their time worrying about protecting forests, catching poachers or keeping carbon out of the atmosphere. But all these things (and more) are driven by humans. Given that it’s easier and cheaper to reduce the human birth rate than it is to address these other issues, why aren’t conservationists more concerned about keeping our population down?
After all, it is estimated that more than three-quarters of the world’s ice-free land has been modified by people. We are already overstepping the planet’s boundaries and our actions are causing climate change and the sixth mass extinction.
By 2050 human population growth alone will threaten a further 14% of the planet’s species; this is on top of the 52% decline in numbers of mammals, birds, reptiles, amphibians and fish over the past four decades.
Only 13 years ago, we were 6 billion; just seven years later, we hit 7 billion and by 2100 we could be as many as 12.3 billion people. Shockingly, with each child a woman has, her carbon emissions legacy is increased six-fold. It cannot be denied that our size, density and growth rate all increase wildlife extinctions.
