Sustainability science is emerging as a transdisciplinary effort to come to grips with the much-needed symbiosis between human activity and the environment. While there is recognition that conventional economic growth must yield to policies that foster sustainable development, this has not yet occurred on any broad scale. Rather, there is clear evidence that the Earth's ecosystems and landscapes continue to degrade as a consequence of the cumulative impact of human activities. Taking an ecohealth approach to sustainability science provides a unique perspective on both the goals and the means to achieve sustainability. The goals should be the restoration of full functionality to the Earth's ecosystems and landscapes, as measured by the key indicators of health: resilience, organization, vitality (productivity), and the absence of ecosystem distress syndrome. The means should be the coordinated (spatially and temporally) efforts to modify human behaviors to reduce cumulative stress impacts. Achieving ecosystem health should become the cornerstone of sustainability policy-for healthy ecosystems are the essential precondition for achieving sustainable livelihoods, human health, and many other societal objectives, as reflected in the Millennium Development Goals.
可持续性科学正在成为一项跨学科的努力，旨在应对人类活动与环境之间急需的共生关系。虽然人们认识到传统经济增长必须让位于促进可持续发展的政策，但这尚未在任何广泛的范围内实现。相反，有明确的证据表明，由于人类活动的累积影响，地球的生态系统和景观继续退化。采用生态健康方法来研究可持续性科学，为实现可持续性的目标和手段提供了独特的视角。目标应该是恢复地球生态系统和景观的全部功能，这可以通过健康的关键指标来衡量：恢复力、组织性、活力（生产力）以及不存在生态系统应激综合征。手段应该是（在空间和时间上）协调一致的努力，以改变人类行为，减少累积的压力影响。实现生态系统健康应该成为可持续性政策的基石——因为健康的生态系统是实现可持续生计、人类健康以及许多其他社会目标的基本前提，这在千年发展目标中得到了体现。
