Get a sneak peek at the massive Millennium Ecosystem Assessment before its official launch on March 30 in nine cities around the world. Billed as the most comprehensive assessment ever of the world’s ecosystems and the impacts of those ecosystems on human health, the four-year study was written by 1,300 experts from 95 countries with another 900 serving as editors and reviewers. The hope is that like the consensus-driven Intergovernmental Panel on Climate Change (IPCC), the pains taken at inclusive and comprehensive scientific assessment will bring more political as well as scientific heft to the conclusions. With the report embargoed until its release March 30, it is hard to say more. But there is something for everyone in this effort.
