This very interesting video from the American Museum of Natural History displaying the growth of the human population on earth (from the beginning to now) has gotten over 500.000 views within days. I think it is a very well done visualization.
“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?”
