Findings. The MA was published in 2005 and made four main assessments: Over the past 50 years, humans have changed ecosystems more rapidly and extensively than in any comparable period of time in human history , largely to meet rapidly growing demands for food, fresh water, timber, fiber and fuel.
What did the Millennium Ecosystem Assessment do?
The Millennium Ecosystem Assessment (MA) is an international work program designed to meet the needs of decision makers and the public for scientific information concerning the consequences of ecosystem change for human well-being and options for responding to those changes .
Is the Millennium Ecosystem Assessment successful?
The MA has had a notable impact on international conservation-oriented NGOs but much less impact on national NGOs. To date, there is no evidence of any impact on NGOs focused on development, poverty reduction, or health issues.

What were the ecosystem services defined in the Millennium Ecosystem Assessment 2005 )?
Ecosystem services are the benefits people obtain from ecosystems . These include provi- sioning, regulating, and cultural services that directly affect people and supporting services needed to maintain the other services. Page 10. 58. Ecosystems and Human Well-being: A Framework for Assessment.
What are the 4 main categories of ecosystem services?
The Millennium Ecosystem Assessment (MA), a major UN-sponsored effort to analyze the impact of human actions on ecosystems and human well-being, identified four major categories of ecosystem services: provisioning, regulating, cultural and supporting services .
How are ecosystem services linked to biodiversity?
Ecosystem services are the goods and services that biodiversity provides. They include soil formation, the provision of food and fibre, air quality and climate regulation, the regulation of water supply and quality and the cultural and aesthetic value of certain plants and species .

What is an ecosystem service example?
Examples of ecosystem services include products such as food and water , regulation of floods, soil erosion and disease outbreaks, and non-material benefits such as recreational and spiritual benefits in natural areas.
How do healthy ecosystems maintain their balance?
A balanced ecosystem works via energy and material cycling . The chief energy source of ecosystems is sunlight. Photosynthesis of sunlight by plants creates oxygen as a waste product, which in turn is used in respiration by animals. Animals, in turn, create carbon dioxide as waste, and that is used by plants.
