Ecology is the study of the relations of organisms, or of whole local ecosystems, to their environments. The field is often called environmental biology. Its practitioners might be trained as biologists, botanists, or other natural scientists. Their work frequently involves pure research in a university of government agency setting. Conservationists devote their careers to the protection and wise use of our natural resources, the soil, water, forests, minerals, wildlife, and grazing lands.
Conservation is closely related to ecology, the major differences being in emphasis.
Architecture is the art and science of designing buildings and the spaces between them. Land management is the balancing of one use of land against another to achieve maximum values in keeping with social need, economic considerations, and an environmental ethic. Other environmentalists work in social, political, legal, health, and educational arenas to protect the environment. Their skills include writing, speaking, research, analysis, teaching, training, negotiating and persuading. The work of the environmentalists defies summarization.
