Recently, in my Biology class, we had to calculate our carbon footprint. Before starting, I predicted that my footprint would be low for my area but high compared to the rest of the world. And I was right. My total carbon footprint was 6039 kg of C02 a year, the average in my area was 9727 kg, and the world average was 3791 kg.
Even though I think I have a pretty low footprint to begin with, I still feel a responsibility to make changes to help our planet. After filling out the survey, I began to analyze what was causing the most C02 emissions in each category.
For transportation (1324 kg), I think the biggest factor was driving. My family drives a lot. We love travelling to places in California. However, we rarely take airplanes, which I think it why my footprint for transportation isn't larger. In middle school, I took the bus every day to school. But this year and probably for the rest of high school, I have gotten into a habit of biking to school or walking to local places or when hanging out with my friends. I think that if I made that choice more often, my carbon  footprint would go down. And that's a very easy thing to do.
Home (3281 kg), contributed most to my footprint. I think that is because of all my light bulbs. I have lots of rooms in my house, and therefore lots of light bulbs. I try to remember to turn off the lights when I'm not in the room, but sometimes I forget. Sometimes I spend hours in the same room with the lights on finishing my homework because it's dark. A change I can make here is try to do my homework and other activities earlier when it's still light so I don't need to keep the light bulbs on all night.
Food is pretty low (1096 kg). I usually eat vegetarian meals (always for breakfast and lunch), but I have meat for dinner. I didn't know that eating meat would contribute to your carbon footprint! Well, I'm not ready to give up meat completely, but perhaps if I ate less of it, my footprint would decrease.
Lastly, purchases (339 kg). I always buy my clothes second-hand. This way, I can find more unique clothing, they're cheaper, and I'm reusing. I also donate my old clothing to charities. I like to know that my almost-never-worn clothes can be used by some other person. The clothing industry doesn't always have to make new clothes and waste cotton, at least not for me. One way I could reduce my footprint in this category is to be more aware of the packaging. Before, I rarely or ever thought about that. But now that plastic bags are gone in my city, I realize how much packaging goes to waste when people buy and that if we were more aware of it and bought less-packaged items we could save a lot of plastic!
I've figured out a few little ways I can reduce my footprint, and I hope you can too!

Your carbon footprint was much lower than my average. You are doing a pretty good job keeping your numbers low. Your transportation was far less than mine, close to 6,000 less.
