It took us 200,000 years to reach 1 billion human beings on Earth, and just 200 years to reach 7 billion. In 2050, when the world population reaches 10 billion people, only 2 billion or so will be living in industrialized countries. For the remaining 8 billion people- more than the present Earth's population- food security will require access to that which grows from the ground and falls from the trees, and most of those vegetables, nuts and fruits depend upon pollinators to reproduce.
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?
