Unit 6 Test

Select all of the correct statements about per capita resource use.

• As population increases, the rate of per capita use affects whether a resource is renewable.

• Resources such as coal and natural gas can be renewable if annual per capita consumption of those resources decreases.

• The overall use of natural resources is relatively high in industrialized nations even though population growth is slower in those nations.

• How long a natural resource will last can be predicted by evaluating the per capita consumption of that resource and the rate of population growth.
