Billions! In 1997 there were about 5,840,000,000 human beings living on our planet. That's more than twice as many as 50 years ago. Are there more and more people? Every minute, 167 babies are bom around the world. Imagine how they would cry if they were all put together! By the year 2025 there will probably be 8,036,000,000 people in the world.
