Once you start thinking about humans as a species in a biome, it affects your entire way of looking at normal things.
The other day I referred to female morning joggers as an 'indicator species' in that if you see women jogging in the dark it means that the environment provides migration pathways (sidewalks, clear signs) and doesn't have any known predators of female morning joggers (guy with knife, bear, BigTruck, male morning joggers).
Though, I think that people consider framing humans as animals reacting to their environment as rude.
