Rebuilding marine life

Sustainable development Goal 14 of the United Nations aims to "conserve and sustainably use the oceans, seas and marine resources for sustainable development". Achieving this goal will require rebuilding the marine life-support system that deliver the many benefits that society receives from a healthy ocean. Here we document the recovery of marine population, habitats and ecosystems following past conservation interventions. Mitigating the major pressures like climate change could help in achieving structure and functional marine life by 2050. By rebuilding marine life represents a doable Grand Challenge for humanity, an ethical obligation and a smart economic ojective to achieve a sustainable future.
