New unit

Today in class, we started a new unit about population and settlement. Some of the terms we're going to have to know are life expectancy, birth rate, death rate, immigrant, and emigrant. today we talked about how 7.6 billion people are on the earth right now. Our earth increases by 200,000 per day, 8377 per hour, 149 per minute, and 2.5 per second. We also talked about the population clock. It's crazy to think how fast our population is increasing our population has a constant rate at which it increases. When you think about it, its a bad thing because it will lead to overpopulation which will create a decrease and resources and eventually cause major problems in the near future.
