Alexi's "Pheonix, Arizona"

Alexi's story about life in Arizona is cold and gritty. A cruel and real tale of life at it's bleakest, but there is one point that I want to focus on. The jack rabbit killed itself to get away from Phoenix, Arizona. Desolation and death were constant in this story, but of all things, this rabbit, being the "only living thing left in Arizona, had to die. Why did Alexi describe the jackrabbit as being the only living thing left in Arizona when there are a ton of people living there? It is most likely because all of the people are dead on the inside and are just waiting to die on the outside, too. That is definitely a strong feeling that I get when reading this.
