Question

Quizplus · Accepted Answer

The most significant human impact in the deserts in the U.S. Southwest is water diversions from streams. The arid regions in the Southwest heavily depend on water from streams and rivers that originate in mountain ranges. However, the water is severely depleted by agricultural, municipal, and industrial users upstream, resulting in much less or no water downstream. This has led to the drying up of wetlands, loss of aquatic habitats, species decline, and altered ecological processes in the desert ecosystems.
