Zombiez

Zombies are not only important contributors to society, but necessary in our modern era's ecosystem. Due to the decline of predators of mankind and innovations such as agriculture and medicine, the human population is rapidly increasing. The occasional rampaging zombie horde helps to cull this population, which means increased resources per person, less man made damage to the earth, and a very satisfied zombie population. Like most species, however, mankind is biologically focussed on surviving, which leads to technical innovations to cull the zombie hordes when they get out of hand. This leads to zombie evolution, and so on. This cycle benefits both parties (lol, parties, Pinkie Pie) and helps to manage the population of both so that neither grow large enough to cause lasting damage to their ecosystem. Embrace the zombies, save the planet.
