Author contributions: J.L. and S.A.L. designed research; J.L., E.B.C.-C., J.N.R., and S.A.L. performed analysis; and J.L., E.B.C.-C., J.N.R., and S.A.L. wrote the paper.(ten). These impacts pose significant challenges for the continued provisioning of ecosystem services in the fpsyg.2015.01865 ocean: challenges that could seem overwhelming now, but even more so in light in the difficulties in addressing the complicated drivers and reversing trends. In quick, threats to ocean life and the provision of important ecosystem services are unquestionably significant and pressures on ocean sources are escalating. Glimmers of Hope for Sustainable Use of your Ocean Regardless of these daunting challenges, there's reason for cautious fnins.2015.00094 hope. Around the globe, a lot of optimistic adjustments are underway: awareness, attitudes, and social norms are changing; economic incentives are shifting; efforts to educate consumers are increasing; new policies are leading to stronger mandates and much more helpful governance, compliance, and enforcement; and practices are changing using the improvement of improved technologies, new goods, and business strategies that reflect the circular economy (11), higher engagement of scientists, and improved understanding of trade-offs. Because of this, powerful models for modify based in naturalThe grand challenge for humanity should be to meet the basic needs of people today in an equitable manner these days although simultaneously restoring and maintaining ecosystem functioning for future generations. We must do so inside the face of increasing numbers of folks as well as the concomitant will need for resources, and with environmental adjustments, like climate adjust, already underway. The ocean is integral to this international mission. Ocean and coastal ecosystems provide a range of important ecosystem services that people rely upon, including meals, oxygen, climate regulation, handle of pests, protection from storm surges, recreational possibilities, and cultural worth (1, 2). The ocean is house to wealthy biodiversity and plays crucial roles in quite a few global processes, from key production to nutrient cycling to climate and weather (three). Ocean-based activities and livelihoods are both enabled by and have an effect on complicated interactions among ecological, social, and financial systems. The international marketplace value of marine and coastal resources and industries is estimated at 3 trillion per year (4). More than 3 billion persons depend upon the oceans to supply their main source of protein, and marine fisheries directly or indirectly employ over 200 million persons (4).

Holistic approaches bring hope for individuals as well as the ocean," presented by Jane Lubchenco on March 14, in the National Academy of Sciences in Washington, DC. The lecture was element in the Arthur M. Sackler Colloquium of the National Academy of Sciences, "Coupled Human and Environmental Systems," held March 14?five.
