Encyclopaedia of Human Ecology

The humans, like all other species on Planet Earth interact with each other during their span of life. Humans constitute a part of the Earth's biomass. The biomatter constituting the human frames has been tossing right through the history of time when the humans first evolved. During this span of millions of years of the humans have interacted within their own species, as well as with other species, down the geological history. The evolution continues, and so does the interaction. Each development caused through human interventions augurs fresh interactive cycles.
