Over the years, human activities have impacted the natural resources of Lake Mead National Recreation Area in many ways. Humans have introduced non-native plant and animal species into the park, which out compete native flora and fauna for space, food and water. The park is a “living laboratory” that helps us understand how environmental factors have shaped this desert ecosystem and how they may be changing it at present. It also shows the sharp contrast between a less-disturbed ecosystem and the completely human-shaped one in the urban areas nearby.
