The Millennium Development Goals are eight goals (with 21 quantifiable targets that are measured by 60 indicators), adopted by countries in 2000 to be achieved by 2015. They are based on the Millennium Declaration endorsed by 189 Heads of State at the UN General Assembly. All the goals are closely inter-related, including their indicators. That is, the implementation or negligence of one goal can have a positive multiplier effect or decrease the effectiveness of efforts made to achieve the other goals. While there is a temptation to let frustration and disappointment reign due to the slow pace at which governments are implementing their commitments and the endless efforts to re-state the need for a "sustainable development" approach to development, the small steps made should be recognized, particularly given the current financial, economic and social situations. The environmental movement should persist and enhance its work to make the case and showcase those examples where investing for nature has made a difference, environmentally, socially and economically.
