What is the sociological/biological/evolut鈥?reasoning behind the love for animals (pets) and nature?

I am curious to why we love our pets, but will settle for a simple conclusion.What is the sociological/biological/evolut鈥?reasoning behind the love for animals (pets) and nature?People love their pets because it is in human nature to become attacted to things. Think of lovers, workoholics, gluttonous or greedy people. Animals, especially pets, develop their personalities based on their owners. This creates a compatitble match between owner and pet, causing a connection. However there are humans that do not respond to attentions of others and these are those that dislike animals. but generally, pets give us unconditional love, which inclines us to respond.
