A piece of land may be bought for $600,000 to be strip-mined for coal. Annual net income will be $500,000 a year for 10 years. At the end of the 10 years, the surface of the land will be restored as required by a federal law on strip mining. The reclamation will cost $1,500,000 more than the resale value of the land after it is restored.
