The most important detail would be the water and its preservation.
The western part of the United States is a region that has an ever-growing population. This has resulted in numerous environmental problems, that only seem to become bigger and more alarming as the time passes on.
The biggest problem of all is definitely the water, its usage, and its preservation. This region doesn't have big reserves of water, but despite that, the preservation and usage of the same is at a low level. Instead of planting crops or fruit trees that do not require lot of water, big portion of the farmlands are the total opposite, planted with highly demanding crops and fruit trees for water. Because of that, most of the groundwater has been already used, and that has been the largest source of freshwater in the region. The pollution of the rivers is also a big problem, because making the water not suitable for drinking, with having such small reserves, can easily lead to a disaster.
