The Millennium Ecosystem Assessment was called for by the United Nations. It assessed the consequences of ecosystem change for human wellbeing and the scientific basis for action needed to enhance the conservation and sustainable use of those systems and their contribution to human wellbeing. The findings provide a state-of-the-art scientific appraisal of the condition and trends in the world’s ecosystems, the services they provide, and the options to restore, conserve or enhance the sustainable use of ecosystems.
In February 1939, as part of the Wisconsin Farm and Home Week observance at the University of Wisconsin, Aldo Leopold presented an address entitled “The Farmer as a Conservationist”.
Leopold began his remarks with these words:
“When the land does well for its owner, and the owner does well by his land—when both end up better by reason of their partnership—then we have conservation. When one or the other grows poorer, either in substance, or in character, or in responsiveness to sun, wind, and rain, then we have something else, and it is something we do not like."
