Six billion, seven billion...ten billion? That’s right, Earth’s population could reach close to 10 billion by the end of the century. Can the planet really support that many people? In this BrainPOP movie, Tim and Moby look into how human populations put pressure on the environment, and what we can do to minimize our impact. Tim teaches you the history of population growth, too, explaining why it began to explode several hundred years ago. And you’ll get the scoop on how technologies like medicine and sanitation got us to this point!
