Carbon dioxide $\left(\mathrm{CO}_{2}\right)$ is the gas that is mainly responsible for global warming (the greenhouse effect). The burning of fossil fuels is a major cause of the increased concentration of $\mathrm{CO}_{2}$ in the atmosphere. Carbon dioxide is also the end product of metabolism (see Example 3.13 ). Using glucose as an example of food, calculate the annual human production of $\mathrm{CO}_{2}$ in grams, assuming that each person consumes $5.0 \times 10^{2} \mathrm{~g}$ of glucose per day. The world's population is 7.2 billion, and there are 365 days in a year.
