One of the most pressing issues in the Phoenix metropolitan area right now is water, specifically the allotment and conservation of it since supply is limited. What’s becoming clear as the water crisis rages is that desert cities and their inhabitants are going to have to get creative in the face of climate change, but the solution for many may very well be found in a decades-old tourist attraction. No institution knows the value of native foliage better than Phoenix’s Desert Botanical Garden, a verdant park that takes visitors into what life in Arizona is really about.
