Question

Quizplus · Accepted Answer

The clause "use without impairment" is the most relevant to the controversy over damming in National Parks. This clause specifically states that the National Parks should be used for recreational purposes, but not at the cost of damaging the environment. Damming could cause significant harm to the ecosystem and wildlife in the area, which goes against the Park Service's mission of using the parks without impairing them.
