Ecocide

Ecocide is the killing of an ecosystem, which includes consuming it and using it to feed some other process or system - ecophagy. There are however ways to render an ecosystem not viable that do not require consuming or crushing all of its parts. It is thus a serious mistake to assume that measures to prevent ecophagy or conversion of the living matter to non-living matter, necessarily will prevent ecocide.

Criteria for life

A difficult question is whether an ecosystem is alive in the sense of a single living organism. Any form of lifehas a form of homeostasiswhich keeps it at maximum entropy, that is, shedding heat. Meanwhile, its internal life processes are negentropic, increasing the degree of order of matter in the body. This, along with the ability to reproduce, are usually cited as the two most important attributes of any life form.

Reproduction

An ecosystem typically has a homeorheticequilibrium rather than a full homeostasis. However, a virusor prionor molecular assembleror perhaps a clanking replicatoralso lacks their own reproduction, homeostasis, and thus full status as a life form, but it would not be difficult to identify when they had been "killed", i.e. lost their integrity or "died", unable to perform their normal functions any more.

Resource

From a strictly human point of view, the most reasonable way to assess the life or lack of life of any ecosystem is whether it is capable of an ecological yieldof fresh air, clean water, and other nature's services, on which our own lives depend. Aside from being an aestheticor ethicalissue, it is a matter of sheer survival for those who depend on the endangered ecosystem in any way.

Depletion

From this point of view, there are many known cases of utter disabling of nature's services due to pollution, erosion, loss of topsoildue to strip miningor overintensive agriculture- perhaps leaving a minimal ecosystem such as a desertnot capable of performing the same services or life forms as prior to the ecocide, flooding, saltintrusion - such as due to shrimp farming, and (most commonly) deforestation.

Examples

This last is a signal case often cited by ecologists, who refer to Easter Island Syndromeas evidence that human beings may be naturally inclined to ecocide, and do indeed shit where they live, as the popular expression (and the song Humans Are Stupid, by Mendelsohn Joe) suggests.

Related concepts

The related concept of dieoffin population biologyrefers to the precipitous drop in any population once it has overgrazedits environment to the point where it is simply no longer viable as a population. This usually occurs far before a full-spectrum ecocide, however, as few organisms consume a wide range of foods, nor directly transform (or "terraform") ecoregionssimply to serve their own purposes. Thus total extinctionof all life seems unlikely.
