Abstract
The losses that are being incurred of the Earth's biological diversity, at all levels, are now staggering. The trend lines for future loss are steeply upward as new adverse drivers of change come into play. The political processes for matching this crisis are now inadequate and the science needs to address this issue are huge and slow to fulfil, even though strong advances have been made. A more integrated approach to evaluating biodiversity in terms that are meaningful to the larger community is needed that can provide understandable metrics of the consequences to society of the losses that are occurring. Greater attention is also needed in forecasting likely diversity-loss scenarios in the near term and strategies for alleviating detrimental consequences. At the international level, the Convention on Biological Diversity must be revisited to make it more powerful to meet the needs that originally motivated its creation. Similarly, at local and regional levels, an ecosystem-service approach to conservati...
