Question

Describe the effects of strip mining on the land.

How many human activities be related to desertification?

Answer 1

Strip mining makes barren hills. These areas can be reclaimed, but usually only at great expense. By way of perspective, strip mining is generally only utilized in areas of "waste land" where shaft mining methods would prove impossible.

Human activities leading to desertification can include strip mining, overlogging, overgrazing, and exhausting soil of nutrients (overfarming).
