what I learned from chapter 6

Something that I learned from chapter 6 is that there are several plans to reduce carbon dioxide. The saddest thing for me is that most of the people including me do not realize that we are responsible and contributors in the pollution of the environment. Another interesting thing that I learned from this chapter is that we should start replacing vehicles, and try to replace it by using bicycles, public transportation. We should begin to walk more often instead of using our car for everything; moreover, walking is beneficial for our health. Walking or cycling emits 0Kg of CO2  associated with the burning of fossil fuels; we should try everything to clean our world.
