Table:Global crude birth and death rates from 2003 to 2011

the global birth-and-death-rate table shown above below shows the crude birth rate and the crude death rate per thousand of the global human population between 2003 and 2011.

Outline one way in which a larger world population may cause an increase in the rate of global warming.

larger population uses more energy/fossil fuels, so produces extra carbon dioxide/greenhouse gases;
larger population uses more land for growing food eg rice / keeps more livestock, so produces extra methane/greenhouse gases;
more people results in more respiration increasing $\mathrm{CO}_{2}$ and contributing to global warming
