For Each Strategy and Analogous Opposite

Although the concern here is the reduction of damage produced by energy transfer, it is noteworthy that to each strategy there is an opposite focused on increasing damage. The latter are most commonly seen in collective and individual violence–as in war, homicide, and arson. Various of them are also seen in manufacturing, mining, machining, hunting, and some medical and other activities in which structural damage often of a very specific nature is sought. (A medical illustration would be the destruction of the anterior pituitary with a beam of ionizing radiation as a measure to eliminate pathologic hyperactivity.) For example, a maker or motor vehicles or of aircraft landing-gear struts–a product predictably subject to energy insults–could make his product more delicate, both to increase labor and sales of parts and materials, and to shorten its average useful life by decreasing the age at which commonplace amounts of damager increasingly exceed in cost the depreciating value of the product in use. The manufacturer might also design for difficulty or repair by using complex exterior sheet metal surfaces, making components difficult to get at, other means.

The type of categorization outlined here is similar to those useful for dealing systematically with other environmental problems and their ecology. In belief illustration, various species of toxic and environment-damaging atoms (such as lead), molecules (e.g. DDT), and mixtures (garbage and some air pollutants, among others) are marshaled, go through series of physical states and situations, interact with structures and systems of various characteristics, and produce damage in sequences leading to the final, stable results.

Similar comments can be made concerning the ecology of some of the viral, unicellular, and metazoan organisms that attack animate and inanimate structures; their hosts; and the types and stages of damage they produce.*

Sufficient differences among systems often exist, however–for example, the ecology of the agents of many arthropod-borne diseases is quite complex, and the life cycles of organisms such as schistosomes require two or more different host species in sequence–to preclude at this time many generalizations useful across the breadth of all environmental hazards and their damaging interactions with other organisms and structures.
