Aquatic ecology

Freshwater chapter AP Environmental case study: The case study for this chapter is centered on the Colorado River and Las Vegas. The river supplies many states with the necessary water for people to live in the area, but as of late the river has been drained. This is due in part to the city of Las Vegas using ?more than their fair share? of the water. The city is in the middle of a very dehydrated area and as a result the city uses more and more water each year as it grows. This is considered and environmental concern in that the freshwater from the river is being consumed at a rate considered to be unsustainable to the current state of freshwater usage. Without any signs of water usage slowing in Las Vegas and other cities, the river is gradually being drained away.
