Population

Today we started our second unit which is about population and migration. We learned more about the population of the world today rather than migration. I know we are going to start discussing that later. There are many things we talked about that kinda made me worry. We talked about the life expectancy of many countries. Life expectancy means the average number of years to be lived by a group of people born in the same year. The US is number 50. The women life expectancy is around 82 and the men are around 70. I didn't expect the US to be in the top ten or anywhere near number 1. I think that because of how people in the US take care of themselves. Our diet isn't where it should be and that is very true for young people. I feel like other counties have it more figured out than we do. I am not saying we aren't developed, it's just we need help in some areas. Such as diet, how we take care of our bodies and much more. There are so many people in the world and the number keeps increasing very quickly. There are over 7 billion people in the world and everyday that number keeps going up. The number also increases by over 73 million a year. 90% of this population growth takes place in the developing countries of Africa, South and East Asia and Latin America. Some countries are fully developed and some are still trying to develop. For the most part, the US is developed. Other places like Africa, aren't as developed as they should be. This could be because of the cause of many things. It could simply be because they have technology but it is not as advanced, or maybe they don't have technology at all. It could also be because some countries in Africa are poor and don't have the vital resources for the people who live there. Many other countries all around the world are the same. These statistics show just how much the world changes all the time.
