A carbon footprint is the total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in equivalent tons of carbon dioxide. When you drive a car, the engine burns fuel which creates a certain amount of CO2, depending on its fuel consumption and the driving distance. When you buy food and goods, the production of the food and goods emits some quantities of CO2. Considering all of these common factors in our daily lives, we need to be more aware of how our choices will affect the earth. The carbon footprint is a very powerful tool to understand the impact of personal behavior on global warming. I was shocked to see that I emit 14 tons of CO2 just from these activities. I think that if you personally want to contribute to stop global warming, the calculation and constant monitoring of your personal carbon footprint is essential. One area where I will reduce my carbon footprint is in transportation. I will walk or bike to class instead of driving my car. I will also try and carpool more often with my friends. I hope these changes in my daily routine will make an impact on this earth for the better.
