Why would it be useful to learn how to communicate with animals?

When we start communicating with animals we find there is much more to our fellow species than we first thought and our relationship blossoms and our understanding increases with all life. Animal communication increases harmony, empathy and compassion between species. It helps us to evolve as a sentient being of the animal kingdom and to recognize our co-species as just that, our animal-relatives, our brothers and sisters of biodiversity.
