Environmental Ethics is the application of ethical behavior to the natural world around us. The concept of applying this ethical behavior to the natural world is often attributed to Aldo Leopold one of the first persons to put into words the the key principles involved in this way of thinking and behaving.
“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. A land ethic, then, reﬂects the existence of an ecological conscience, and this in turn reﬂects a conviction of individual responsibility for the health of land. We can be ethical only in relation to something we can see, feel, understand, love, or otherwise have faith in. The land ethic simply enlarges the boundaries of the community to include soils, waters, plants, and animals,or collectively: the land.” - ALDO LEOPOLD
"In short, a land ethic changes the role of Homo sapiens from conqueror of the landcommunity to plain member and citizen of it. It implies respect for his fellow-members, and also respect for the community as such." - ALDO LEOPOLD
