. Ecosystems and Human Well-Being: Biodiversity Synthesis. increasingly important component of response measures (, S7, R5). The world in 2100 could have substantial remaining biodi- versity or could be relatively homogenized and contain rela- tively low levels of diversity. Sites that are globally important for biodiversity could be protected while locally or nationally important biodiversity is lost. Science can help to inform the costs and benefits of these different futures and identify paths to achieve them, along with the risks and the thresholds. Where there is insufficient information to predict the consequences of alternative actions, science can identify the range of possible outcome. Science can thus help ensure that social decisions are made with the best available information. But ultimately the choice of biodiversity futures must be determined by society. Figure Trade-offs between Promoting Human Well-being and Limiting Biodiversity Loss under the Four MA Scenarios to 2050 (, S10) Loss of biodiversity is least in the two scenarios that feature a proactive approach to environmental management (TechnoGarden and Adapting Mosaic), while the Global Orchestration scenario does most to promote human well-being and achieves the fastest progress toward the MDG of eradicating extreme poverty. The Order from Strength scenario performs badly on both sets of objectives.
