Chapter 8 -- Jennifer E

According to The Sixth Extinction an Unnatural History, on page 162 it states, “Warming today is taking place at least ten times faster than it did at the end of the last glaciation, and at the end of all those glacification that preceded it. To keep up, organism will have to migrate, or otherwise adapt, at least ten times more quickly.” This shows that due to the chemicals released in the atmosphere, the global temperature will start to increase. It pushes animals to migrate in order to supply or to adapt. This overall connects to the theme natural systems change over time and space. In this case the natural system is the weather. If the weather is rising, it’ll force animals and other organism to adapt or move in order to survive. This connects to polar bears losing their habitat due to global warming. Because of the rise in temperature, the arctic sea ice is melting. This cause the polar bears to lose their habitat.
