end of chapter 24

This last part of the chapter is about the worlds environment and the globalization of environmentalism. The three main factors that magnified human impact was the population increase, use of fossil fuels, and economic growth. I was shocked to read that the population quadrupled. That is a lot to increase in the twentieth century. These three spread all over the world which led to the globalization. The map on page 748 was pretty interesting. It showed the distribution of the increase of population. Global warming became the concensous in 2000 from the burned fossil fuels that are thinning the ozone layer. Im really not too sure what this actually means. But in the ninteeth century environmentalist emerged. It began in the west with rachel carson. I have heard of the green party before but I never knew it corelated to the environmentalist so I thought that was pretty cool to find that out. Environmentalism became a global concern and still is today. The picture on 751 was really interesting. It showed the environmentalist portest in korea. Their masks were kind of scary, but i didnt really get the point of wearing the masks. I was really shocked to see that the US alone contributes 30% to global warming.
