Chapter 12 Response

Chapter 12 started with Darksyde’s wife asking why diet cola fizzles when it is hot. He then went into a discussion about the discovery of black powder and how it led to the invention of more powerful weapons such as guns and steam engines. We then read about the first refrigeration devices of our time, and how the chemicals used in them emitted a large amount of carbon dioxide.
The chapter ended with a discussion about CFCs and global warming. This is a concept that we always hear talked about in the news media today, but I have really never paid much attention to it. Mr. Darksyde really put it into perspective with the concluding example about the diet soda and how the oceans could really do the same thing if our ozone layer continued to deteriorate and global temperatures continued rising. This would be something that would make earth’s land virtually uninhabitable, and kill off a large amount of the human race. After reading this chapter, I think I will be more inclined to pay attention when I hear something about global warming from now on!
