DEFINITION OF A BALANCE OF NATURE

By C. A. Harwell

Nature has through the course of time maintained a balance between various forms of life, both animal and vegetable, and their environment (climate, exposure, soil, etc.). This is a dynamic balance, events traveling in cycles, rather than establishing a static equilibrium.

Actually there is no fixed balance or cycle of events, for otherwise there would be no permanent evolutionary or other biological major changes.

Through the agency of geological changes, climatic changes, biological changes, man and natural catastrophe, the balance of nature may be disturbed, changes taking place such that eventually a new life cycle is established.
