	11. A keystone species is a profound influence on a community in excess of that expected by its relative abundance. Because they are so vital to the environment it seems obvious that those species are the ones that need to be protected.		11.

	8. I couldn't find something in the book that would answer this question, so I attempted using logic. Perhaps, since ther are less plants in the world, due to forest destruction. There is less photosynthesis, therefore leaving more carbon in the air maybe release less heat and light. So, the temperature would go down??? I thought that the temperature was going up in the world. In which case, my philosophy would be wrong.		8.

	12. Troposphere and the stratosphere. The troposphere has turbulent wind, where as the stratosphere has a steady wind but no turbulance. The tempuratures are also different between the two layers. Troposphere is where we live and the tempuratures are made for us to be in. The stratosphere loses 6 degrees ever km upwards.		12. Troposphere and the stratosphere.
