The earth's ecosystems provide goods and services that are essential to human existence, yet many of them are directly threatened by human activities. A coordinated international effort is needed, to assess the current and probable future state of ecosystems worldwide. An international ecosystem assessment is desirable to meet the needs of sustainable development and to foster a shift to predictive management of resources.

The authors are members of a Steering Committee exploring the merits of launching a Millennium Assessment of the World's Ecosystems.
