This is occurring throughout the arid western states. Now examine Figure 21.3, page 538. You read in the first pages of this chapter that oil is a nonrenewable resource. That means that one day, the oil will run out.
Most geologists agree that the big oil fields have already all been discovered.
Combine that with the rapidly-increasing population, and it means our oil will run out even faster. Other nations are naturally anxious to raise their standard of living to approach the United States. Project this scenario 50 years into the future. Briefly discuss three environmental effects of burning fossil fuels. Study Figure 21.8, page 543.
