It is not possible to understand the apparent stability of the Earth's climate and environment unless we can fully understand how the best possible environmental conditions may be maintained for life to exist. Human colonization of areas with natural biota, for industrial or agricultural activities, will lead to degradation of those natural communities and violation of the BRE (biotic regulation of the environment) principle. Thus to maintain an environment on Earth that is suitable for life it is necessary to preserve and allow the natural recovery of natural biotic communities, both in the oceans and on land. This book is devoted to a quantitative version of the BRE concept, and is built on a foundation of modern scientific knowledge accumulated in the fields of physics and biology.
