I think that a big factor in teenage carbon footprints is transportation. Our city has a lot public transportation that is available to our community. AC transit and BART should be utilized more by teenagers today. I try my best to use these public transportation systems as often as possible, and so should all teens today. I believe that by doing so, our city and carbon footprints will benefit.

I agree transportation was a big thing in my carbon footprint. AC transit and Bart can help me a lot with that situation. It can also help our community's carbon footprint average. A lot of people decide not to go on these things because they think it's dirty or nasty. We can all help clean these two transportation systems and finally see a decrease in our carbon footprint. So take action and decrease your carbon footprint today!!

I agree with you. I think that transportation has a big affect on carbon footprints, and it is something that should be changed now. The United States Environmental Protection Agency states, "Transportation (28.9 percent of 2017 greenhouse gas emissions) – The transportation sector generates the largest share of greenhouse gas emissions. Greenhouse gas emissions from transportation primarily come from burning fossil fuel" (EPA 1). This evidence shows how big of an impact transportation has on the greenhouse gas emissions, being the largest contributor to climate change. The fossil fuels that this quote tells us about brings out how toxic the transportation we use on a daily basis is for our planet's life. If people, especially teens, started using public transportation more, it would be very beneficial to the atmosphere.

I agree with you. people  can save more than $9,738 per year by taking public transportation instead of driving. This  can lead to  environmental benefits. If your commute is 20-miles round trip, or even more and you switch to public transportation you  could lower your carbon footprint by 4,800 pounds annually.

I agree that public transportation is a valuable resource for people in urban areas, and that it should be used more frequently by young and old people alike. I understand why you would say that people can save money by taking public transportation, but in the moment, a short car trip which will not directly result in needing to get gas can seem like the more affordable option. According to the BART fare calculator (https://www.bart.gov/tickets/calculator), an adult one way ticket from San Francisco International Airport to Oakland International airport is $17.00. A drive between those two places would have the immediate cost of $0. An obvious solution to this problem is to make public transportation free. Of course, then there is the issue of how the BART operators, AC Transit drivers, etc. would be paid. It is a complicated issue, but it could significantly bring down the area's carbon footprint.
