Right now, human population growth is doing something long thought impossible – it’s wavering. It’s now possible global population could peak much earlier than expected, topping 10 billion in the 2060s. Then, it would begin to fall.
In wealthier countries, it’s already happening. Japan’s population is falling sharply, with a net loss of 100 people every hour. In Europe, America and East Asia, fertility rates have fallen sharply. Many middle or lower income countries are about to drop too.
