The Millennium Ecosystem Assessment Synthesis Report boils down the findings of the four working groups into a simple, straightforward description of Earth's ecological health and its linkages to human well-being. It answers a series of key questions, such as: How have ecosystems changed over the past 50 years? What are the most critical factors causing ecosystem damage? What options do we have for better conserving, restoring, and benefiting from ecosystems? The volume then presents a snapshot of the health and prospects for each of the main services that ecosystems provide, including the provision of food, water, timber, fuel, climate regulation, disease prevention, and others. The Synthesis Report will prove ideal for students and laypersons interested in a quick, but nuanced, understanding of the state of Earth's ecosystems.
