Population and Settlement

          Today we started a new unit about population and settlement. There are 7 million people on the planet today. I learned that the US is ranked 50 in the world. If you think about it that's not very good. This is because of our diet and lack of exercise. People now are going home and sitting in front of the TV and not doing anything active. Peoples diet in the US is decreasing cause of all the processed food. The life expectancy for the US is 78.54 or something around there.
