How is population growth connected to increased demand for energy and to air pollution?

• As the population grows, there is a higher demand for energy. Increased energy use causes more air pollution.

• As the population grows, there is a reduced demand for energy. Decreased energy use causes more air pollution.

• There is no connection.

• As the population grows, there is a higher demand for energy. Increased energy use causes less air pollution.
