Ecology is a field of study whose first law is that everything is connected to everything else.
Ecology is the grand system of the interaction of all elements of the natural world, including plant, mineral, animal, and human.
Ecology is concerned with drawing attention to a thing's necessary implication in a network of relations... with marking its persistent tendency to enter into a working system.
Ecology is the study of the place where, or rather the place 'that' we live (oikos). That place is a dynamic flow of matter-energy that tends to settle into various bodies, bodies that often join forces, make connections, form alliances [where] humans are always in composition with nonhumanity, never outside of a sticky web of connections or an ecology.
Ecology is the biology of ecosystems. It is the study of systems at a level in which organisms are elements of interaction within a loosely organized environmental matrix.
Ecology is a dirty seven-letter word to many people. They are like heavy sleepers refusing to be aroused. 'Leave me alone! It's not time to get up yet!.
Ecology is not a matter of letting the environment go back to the wilderness, but of finding some kind of working balance between man and nature founded on a respect for nature and its inner economies.
