Which assessment comprehensively evaluates the condition of the world's ecological systems and their capacity to continue supporting humanity?

The question is asking for a global, evidence-based evaluation of how healthy Earth’s ecosystems are and whether they can keep supporting human life in the future. The Millennium Ecosystem Assessment fits this description because it was a major international effort that synthesized a vast body of scientific work to provide a comprehensive picture of the state of ecosystems worldwide, the services they provide, how human actions are changing them, and what these changes mean for human well-being. It organized ecosystem services into categories like provisioning (food, water), regulating (climate, flood control), supporting (soil formation, biodiversity), and cultural (recreational, spiritual), and it connected changes in these services to potential impacts on people. It also explored future scenarios and policy options to maintain or improve the ability of ecosystems to support humanity, making it the best choice for a global assessment of ecological condition and capacity. Environmental Ethics, by contrast, is a field that examines moral principles and obligations toward the natural world and does not constitute a comprehensive assessment of ecological status. Anthropocentrism is a human-centered viewpoint about value and priority, not an evaluative report on ecosystems. Leopold Ethics refers to a land ethic framework about how humans ought to relate to the land, again not an assessment.
