Consider the changes that the colorado river has undergone, especially as it relates to human activity in the region and the environmental effects of that activity. what social and cultural actions are affecting the river? what changes might the people living in the southwestern u. s. need to adopt?

The Colorado River is facing major environmental changes and is at risk of drying up. Human actions along the river are primarily responsible for these changes. For the past century, farms, towns, and cities adjacent to the river have drawn off freshwater for agricultural or drinking purposes. Additionally, climate change has resulted in more intense droughts and less rainfall, which also contribute to the river’s shrinking size.

Most major cities in the region will need to drastically reduce the amount of water they take from the river basin. Las Vegas, Nevada, for instance, is a city of 2 million people, but it uses a small amount of water from the Colorado River compared to other cities in the region. Las Vegas laws impose water restrictions on people in the city. Other cities in the region will ultimately need to adopt similar rules and regulations to prevent the river from drying up.
