24. Carbon footprint: Carbon dioxide (CO₂) is produced by burning fossil fuels such as oil and natural gas, and has been connected to
global warming. The following table presents the average amounts (in metric tons) of CO₂ emissions for the years 1997-2013 per
person in the United States and per person in the rest of the world.
