9.5 Global Climate Change question 1

[Maximum number: 1]

As the human population continues to grow, the demand for animal protein is expected to double by 2050. Animal protein can be obtained from conventional livestock and other sources. The production of all animal protein has environmental costs, as shown in the following graphs. In Figure 1, global warming potential (GWP) is measured in kilograms of carbon dioxide equivalent (kgCO2−eq)\left(\mathrm{kgCO}_{2}-\mathrm{eq}\right). Carbon dioxide equivalent is a measure of the warming effect of a gas relative to that of carbon dioxide. In Figure 2, land use is measured in meters squared ( m2\mathrm{m}^{2} ).
