What is Ecology?
Ecology is a distinct branch of biology which is primarily focused on the examination of all living organisms in the natural environment. An ecologist will look at how organisms interact with the environment and each other and particularly, how they study the complex and interconnected systems which influence all life on planet Earth.
In the 20th and 21st centuries, ecology became interested in how human activity and interaction affected the natural environment; ecology ultimately recognized that human beings could have a tremendous affect, in one or another, on our natural ecosystems. For instance, a generic ecology study will focus on the effects that stem from dumping pollutants into a river and how this action can precipitate a variety of changes in nature.
Modern-day ecology will often inspect entire ecosystems and subsequently study all of the organisms which live in the environment and influence it. Each ecosystem will host unique animal species and plant life, which ultimately have adapted to the system and each other. Ecology will focus on the evolutionary path of these species and the history of the ecosystem to create a theory or establish an understanding regarding how the connections between the two variables molded into one.
