Ecological Threshold

Ecological threshold can be described as the point at which a relatively small change in external conditions causes a rapid change in an ecosystem. When an ecological threshold has been passed, the ecosystem may no longer be able to return to its state. The trespassing of ecological threshold often leads to rapid change of ecosystem health.

Famous quotes containing the words ecological and/or threshold:

    It seems to me that there must be an ecological limit to the number of paper pushers the earth can sustain, and that human civilization will collapse when the number of, say, tax lawyers exceeds the world’s total population of farmers, weavers, fisherpersons, and pediatric nurses.
    Barbara Ehrenreich (b. 1941)

    The poorest man may in his cottage bid defiance to all the forces of the Crown. It may be frail—its roof may shake—the wind may blow through it—the storm may enter—the rain may enter—but the King of England cannot enter!—all his forces dare not cross the threshold of the ruined tenement!
    William Pitt, The Elder, Lord Chatham (1708–1778)
