One thought on “How did we get to 7 billion so fast?”

  1. I wonder why certain countries grow at such a fast rate. It can’t be just poverty because there are poorer areas than India and China. There’s way too many people today and there’s no way the Earth can sustain 10 billion unless we become that utopic society that doesn’t create harm to the environment. Anyone that knows anything about humanity knows that this isn’t possible.
