Final answer:
Access to fresh water is an important topic in geography. Freshwater is not evenly distributed across the planet, and many people around the world do not have access to enough clean water. Water scarcity is a serious resource problem globally.
Step-by-step explanation:
Access to fresh water is an important topic in geography. Freshwater is not evenly distributed across the planet, and many people around the world do not have access to enough clean water. This can be particularly challenging during droughts. For example, in Las Vegas, a desert city, 90 percent of the water comes from Lake Mead, a Colorado River reservoir. The availability of water has a significant impact on human settlements, agriculture, and energy production. Water scarcity is a serious resource problem globally.
