Politicians and other advertisers equate ecology with “beer cans and pollution” and environment with “clean air and clean water,” in short thehuman environment. Anthropocentric.All other organisms have environments, too.

Environment is defined as all the physical and biotic factors impinging upon a particular organismic unit, as well as everything affectedby that organismic unit.

An organismic unit could be an individual, apopulation, or even all of the organisms livingtogether in a particular ecosystem, an entire community.

These constitute different levels of organization in the biological hierarchy of life.

Ecology is defined as the study of the interactionsbetween organisms and their environments.

Ecology requires wild organisms in the naturalenvironments within which they evolved and towhich they have become adapted.

Ecology requires wild organisms in the naturalenvironments within which they evolved and towhich they have become adapted.

Once, we were surrounded by wilderness and wild animals, now we surround them.

Anthropocentrism — humans see themselves at the center of the universe.

Captive organisms are out of context, they don’t have a natural environment (they might as well be dead as far as an ecologist is concerned)

Walden “Book of Life” metaphor Holmes Rolston (1985) “Vanishing Book of Life”Humans are just beginning to be able to read it, but its pages are tattered and torn, and entire chapters have been ripped out. Need to save as much as possible (conservation biology), but also must READ it (ecology) before it is gone. Other Earthlings have a right to exist, too.
