Human Health, Well-Being, and Global Ecological Scenarios	2005-02-22		.txt	text/plain	5041	255	45	This article categorizes four kinds of adverse effects to human health caused by ecosystem change: direct, mediated, modulated, and systems failure. For example, O'Reilly and others (2003) concludes, in discussing the potential for further reduction in the ecosystem provisioning service of Lake Tanganyika, that ''the human implications of such subtle, but progressive, environmental changes are potentially dire in this densely populated region of the world, where large lakes are essential natural resources for regional economies.'' Ecosystem services as a significant element in state failure may be underrecognized due to our tendency to discount the future possibility of thresholds or emergence. We have explored how ecosystem services impact human health and have proposed that adverse ecological changes can interact and feedback with dysfunctional social responses, leading to the development of states that we have termed mediated and systems failure.	./cache/cord-005080-r01ii1bu.txt	./txt/cord-005080-r01ii1bu.txt
