confusion of this term with environmentalism
{{quotebox|The first significant contribution to the theory of population ecology was that of [[Thomas Malthus]], an English clergyman, who in 1798 published his Essay on the Principle of Population. Malthus introduced the concept that at some point in time an expanding population must exceed supply of prerequisite [[natural resources]], i.e., population increases exponentially resulting in increasing competition for means of subsistence, food, shelter, etc. This concept has been termed the "Struggle for Existence".

Ecology is an established [[science]], but the term is often confused with or used interchangably with [[environmentalism]].
