Ecosystems and Human well-being. Millenium Ecosystem Assessment

This assessment emphasises on how the ecosystem has been exploited in order to satisfy the needs of humans.The Millennium Development Goals was established in order to assess the conditions that lead to environmental degradation and thus reduce or eliminate the negative impact on the ecosystem. The Millennium Assessment(MA) suggests that the key to an improvement towards a sustainable use of the ecosystem involves different actors, mainly in politics,changes in institutions, governments, technology and social behavior. In order to achieve its goals, the MA suggests that the negative effects or the positive effects of factors that degrade the ecosystem should be addressed first.
