It is a place we live in. Inside it, we are surrounded by a diversity of people, animals and plants.But if 2 environments are to clash eg. sea environment and dessert environment, this might turn into chaos like Insufficient Air, Insufficient Water, Insufficient warmth, Insufficient Light, causing the living things there to move to another habitat, repeating the cycle yet again.
Another scenario would be when man's selfishness causes Global warming etc. where all the living things can do is just die.
