Land in Nevada is largely useless. People had their chance to homestead in Nevada, but they did not bother, because there is no water, and even where there was, the soil is alkali and will not grow anything edible or otherwise useful.
However, if you turn a bunch of goats loose on it, or over graze it, they will eat the scrub plants that do grow there, resulting in their extinction, and what happens is that windstorms will blow alkali dust over into the parts of CA and NV that will support crops and poison the soil there.
If you knew more about desert climates, you might be qualified to be taken seriously on this. I am no expert, but I am a graduate of NMSU, and had friends that studied desert agriculture.
