Environment and life

Biogeography, in its ordinary sense, studies plants and animals and the various factors that control them, considering these distributions as geographical facts that lead to distinguishing specific differences in the Earth's surface.
As for the author of this book, M. S. Anderson, the focus of the topic is the third biological laws that control the links between humans and the environment. For him, the natural environment means things such as the surface, geological structure, and climate. It also means various living organisms, from large animals and forests to microbes and fungi. Hence, the topics that the author addresses are diverse, although this diversity does not deviate from the framework that he defined with his own definition of biogeography.
The author focuses his attention on the direct effects of the elements of the natural environment, and by doing so he aims to highlight a fact that is linked to the core of his idea, which is that man, despite the intelligence and knowledge he has been given, is still an animal with all that this word implies in terms of natural and vital deficiencies, and that the environment has rules that there is no way to disobey. All goodness lies in understanding it and coming to terms with it.
