By MICHAEL IP. Forty years ago, on March 29, 1973, the United States ended its military involvement in Vietnam. Although the war would continue another two years, the South Vietnamese would no longer receive American assistance.
Ecology (from Greek: Î¿á¼¶ÎºÎ¿Ï, house, or environment; -Î»Î¿Î³Î¯Î±, study of) is the scientific analysis and study of interactions among organisms and their environment. It is an interdisciplinary field that includes biology, geography, and Earth science.
But while both fields study ecosystems, environmental biology places more emphasis on the biological aspect. Also, while ecology often focuses on the interactions between species in the same ecosystem, environmental biology focuses on the impacts of human activities on those ecosystems and the species living in them. An environmental biologist investigates the impacts of actions, pollutants, and conditions on wild communities.
