Look no further. To understand the state of the planet’s ecosystems, and how far they are threatened by collapse, and to what extent these threaten our well-being we refer you to The Millennium Assessment. It was launched by U.N. Secretary- General Kofi Annan in June 2001 and was completed in March 2005.
The work of hundreds of scientists from every corner of the globe, the research assesses the state of the Earth’s ecosystem from the point of view of its ability to provide us well-being.
The MA synthesizes information from the scientific literature, datasets, and scientific models, and includes knowledge held by the private sector, practitioners, local communities and indigenous peoples. All of the MA findings undergo rigorous peer review. More than 1,300 authors from 95 countries have been involved in four expert working groups preparing the global assessment, and hundreds more continue to undertake more than 20 sub-global assessments.
