In my Carbon Footprint, a large portion was taken up by transportation. I drive to and from school, different sports practices, and places on the weekends. How does this really affect our world? According to the Center for Biology, the U.S. alone, transportation makes up one third of the climate damaging emissions. In California, transportation is the number one contributor to production of greenhouse gasses. These gasses trap heat which causes a rise in global warming, affecting all humans. Also, they can we toxic at high levels. What can we do? It's simple. We can walk. I can't walk all the way to school, or practices but I can walk to places like the grocery store and to the bus stop. I walk many places that include friends houses, the store, and church. Walking is also a good source of exercise  and has many benefits  that contributed to others and yourself.

I agree I think walking and biking places as well as taking public transportation would help as well.  Personally I carpool to school with two other people or join a carpool with five other people on some days.  This website (shown below) also says that when flying in an airplane, flying in economy class is best because the fuel is spread over more people as opposed to flying in first-class or sections with a lesser amount of people.
