ch 23

Chapter 23 talks about the Global interaction and the changes.All over the world the human impact globally plays a big role on our environment. No matter if you are from Europe, Africa, South America, Mexico, China, and many more places we all have one thing in common, we all live on earth. This is our earth and we need to take care of it the best we can because we only have one. This brings me to my next point when Strayer uses the word "Anthropocene era". what this is talking about is the human era. He talked about environmental movements have been starting since the 1960s to see how us humans are impacting the earth including animals and plants. There are three factors that magnified the human impact on earth's ecological system. They include the explosion of human numbers, energy potential of fossil fuels, and phenomenal economic growth. The worlds population quadrupled in a single century. We went from 1.6 billion people in 1900 to over 7 billion people in 2012, it is probably even higher now! The fossil fuels had to deal with coal in the 19th century and oil in the twentieth century. We added things like hydroelectricity, natural gas, and nuclear power.  The last one really coincides with the rest with having modern science and technology increasing the production of goods and services.
