The American Museum of Natural History’s hockey stick graph of explosive human population growth in the last 200 years is projected to increase in the short term, tapering off around 11 billion, give or take several billion depending on a few variables.
It took 200,000 years for our human population to reach 1 billion—and only 200 years to reach 7 billion. But growth has begun slowing, as women have fewer babies on average. When will our global population peak? And how can we minimize our impact on Earth’s resources, even as we approach 11 billion?
Here’s a nice interactive map that looks at the same issue.
