How do we keep the moon unspoiled?

After the gold rush of the 1850s, the Sierra Nevada foothills in California looked like giant moles had attacked. Thousands of mine shafts pocked the landscape. Hydraulic mining devoured hillsides and sent tons of silt into rivers and lakes. Forests went under the axe, denuding hillsides. Millions of pounds of mercury were used to leach gold from ore. To this day, it’s unsafe to eat fish caught in certain areas.This is exactly what space officials want to prevent when we begin to colonize the moon in a few years.
