XV. Read the passage and answer the question.
A carbon footprint is the amount of carbon dioxide (CO2) released into the air by your own energy needs. You need transportation, electricity, food, clothing, and other goods. CO2 is produced by the burning of fossil fuels which is used to provide energy for your homes, by the cars you travel in and by the manufacture and transport of goods you buy.
Carbon dioxide is also called greenhouse gas, which causes global warming. That is the reason why the carbon footprint is a very poweful tool to understand the impact of personal behaviours on global warming. If you want to contribute to stop global warming, the reduction of your personal carbon footprint is essential. Fist, you can reduce your carbon footprint by driving less. When possible, walk or ride a bike to avoid carbon emissions completely or use public transport in order to decrease CO emissions. Second, support using clean energy sources such as wind, solar, geothermal energy and biogas. Finally, reusing or recycling items you no longer use is also a good way to reduce your carbon footprint.
