Question

Modern humans evolved in Africa about 300,000 years ago. Around 100,000 years ago, we began migrating across the globe. The population remained low probably less than 1 million people. It took most of human history for our population to reach 1 billion and just over 200 years to reach 8 billion. But growth has begun slowing, as women have fewer babies on average. Where do you think we are heading in terms of world population growth by 2100?
