Productivity and Stability As Indicators of Ecosystem Health
The importance of stability in community ecology is clear. An unstable ecosystem will be more likely to lose species. Thus, if there is indeed a link between diversity and stability, it is likely that losses of diversity could feedback on themselves, causing even more losses of species. Productivity, on the other hand, has a less clear importance in community ecology. In managed areas like cropland, and in areas where animals are grown or caught, increasing productivity increases the economic success of the area and implies that the area has become more efficient, leading to possible long term resource sustainability. It is more difficult to find the importance of productivity in natural ecosystems.
Beyond the value biodiversity has in regulating and stabilizing ecosystem processes, there are direct economic consequences of losing diversity in certain ecosystems and in the world as a whole. Losing species means losing potential foods, medicines, industrial products, and tourism, all of which have a direct economic effect on peoples lives.

Famous quotes containing the words productivity, stability and/or health:
“It is ultimately in employers’ best interests to have their employees’ families functioning smoothly. In the long run, children who misbehave because they are inadequately supervised or marital partners who disapprove of their spouse’s work situation are productivity problems. Just as work affects parents and children, parents and children affect the workplace by influencing the employed parents’ morale, absenteeism, and productivity.”
—Ann C. Crouter (20th century)
“Every nation ... whose affairs betray a want of wisdom and stability may calculate on every loss which can be sustained from the more systematic policy of its wiser neighbors.”
—James Madison (1751–1836)
“I am astonished at the singular pertinacity and endurance of our lives. The miracle is, that what is is, when it is so difficult, if not impossible, for anything else to be; that we walk on in our particular paths so far, before we fall on death and fate, merely because we must walk in some path; that every man can get a living, and so few can do anything more. So much only can I accomplish ere health and strength are gone, and yet this suffices.”
—Henry David Thoreau (1817–1862)
