Ecology

"That land is a community is the basic concept of ecology, but that land is to be loved and respected is an extension of ethics."

"Many people are under the illusion that before the meddling of humans, the populations of different types of plants and animals tended to be pretty much constant. This isn’t really the way things work, however, in a finite world. Instead, the populations of many species cycle up and down, depending on particular conditions such as the population of animals that prey on them, the availability of food, the prevalence of disease, and the weather conditions. Even forests exhibit surprising variability. Many undergo regular cycles of burning. In fact, some species of trees, such as the giant sequoias in Yosemite, require fire in order to reproduce. These cycles are simply part of the natural order of self-organizing ecosystems in a finite world."

"Even when the pioneer didnt rape Nature, he divorced her a little too easily: he missed the great lesson that both ecology and medicine teach - that Mans great mission is not to conquer nature by main force but to cooperate with her intelligently but lovingly for his own purposes."

"A humbling blow to our arrogant outlook, ecology reveals that humans – who conceive of themselves as the most autonomous and exalted forms of life – are entirely dependent upon the natural world, biodiversity, and in particular, the crucial role nonhuman animals play in maintaining and enriching nature. Indeed, earthworms, dung beetles, butterflies, and bees are far more important to the integrity and diversity of nature than humans are – the latter being the only species one could remove from earth ecosystems with positive effect. From an ecological perspective, humans are an overpopulated, parasitic swarm, living in total ignorance of natural "laws" they foolishly think they can master, but in truth must conform to and harmonize with if they intend to survive."

"If we recognise that every ecosystem can also be viewed as a food web, we can think of it as a circular, interlacing nexus of plant animal relationships (rather than a stratified pyramid with man at the apex)... Each species, be it a form of bacteria or deer, is knitted together in a network of interdependence, however indirect the links may be."

"If we have been slow to develop the general concepts of ecology and conservation, we have been even more tardy in recognizing the facts of the ecology and conservation of man himself. We may hope that this will be the next major phase in the development of biology. Here and there awareness is growing that man, far from being the overlord of all creation, is himself part of nature, subject to the same cosmic forces that control all other life. Mans future welfare and probably even his survival depend upon his learning to live in harmony, rather than in combat, with these forces."
