In the wild, pitcher plants lure in and capture insects/small animals to transforms them into energy once they are dissolved. In lieu of photosynthesis, this carnivorous process contributes to most of the plant's energy producing and consuming needs. Taking inspiration from this natural process, Rat Pitcher is a hypothetical future in which a genetically modified pitcher plant could be installed in various subway tunnels that will lure and dissolve rats for energy.
