Embedded above and on YouTube here: “Human Population Through Time,” a video from the American Museum of Natural History. From the description:
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?
Amazing to see the spikes after agriculture began, and then especially after the industrial revolution.
