  1. The first thing I noticed about deforestation is that it is a type of global warming.I learned that when you deforest trees it causes the carbon dioxide level rise and the oxygen level to lower.If we keep cutting down forests we are going to have less and less trees with more carbon dioxide while we could just go to technology and try to save trees and build on to forests.I can make a connection with deforestation to global warming because deforestation is one of the causes of global warming.I want to know why deforestation will break the ozone layer and how it goes down and deep so far to do that?

  2. I was really surprised when I found out that deforestation can cause an increase in carbon dioxide and a decrease in oxygen. I was also surprised to find out that it causes erosion and less nutrients. I thought that plants took nutrients from the ground making it infertile. I thought that only CFCs broke down the ozone layer not carbon. This is related to my presentation because fossil fuels fuel the machinery that take down the trees. My question is that does carbon break down the ozone layer or carbon dioxide?
