These links deal with using insects and plants from the Mojave desert as food. There are also links to insect farming, which can be done in urban settings and even apartments.
While these food sources are not part of the American diet in general, people throughout the world survive and enjoy eating insects and native plants.
It is worth learning about by anyone who can foresee a need at some future time.
