New Unit on Population+Settlement

Today in Human Geography we started our new section on Population and settlement. I thought maybe first we would get our tests back but there were still people who hadn't done it yet so they had to do it while we were in class. I still already know my score i got a ninety three percent bu ti want to know what i got wrong because i felt really good about the test. Anyway we also talked in class about how many people live on Earth, and about how fast that number has approached today's seven billion. However, we talked about how it was very common for people back in the day to have a lot of kids, and mostly the women took care of the kids. But as time progressed people stopped doing that and would only have one or two kids, which made the population decrease from how fast it was growing. We really ended class that way, With talking about how when my teacher was kid family's had lots of kids and then his generation family's only had a couple, and then future generations of family's had less and less.
