The UN’s Sustainable Development Goals aim to ensure the sustainable use of marine resources and to conserve the ecosystems of our oceans, lakes, rivers, and other waters. In addition to providing coastal communities with their livelihood, the UN estimates that our oceans and waters contribute $28 trillion dollars per year in ecosystem services. These benefits include regulating global temperatures, weather patterns, and absorbing atmospheric carbon dioxide.
In particular, Goal 14 seeks to address the challenges of over-fishing, illegal fishing, ocean acidification, and runoff pollution. The UN has set the following targets:
- Address and minimize the consequences of ocean acidification
- Restore ocean ecosystems, with special attention to strengthening their resilience
- Protect and conserve at least 10 per cent of coastal and marine areas
- End overfishing, illegal fishing, and work to conserve at least percent of coastal and marine areas
Assist least developed and small island nations in their use of marine resources through financial assistance, knowledge and technology transfer, and protective legal frameworks
The stories in this collection illustrate solutions to Goal 14. We learn about how coastal communities are rethinking their relationship to the sea, hoping to make life below water more resilient, and their own livelihoods sustainable. In the Philippines, residents have gone from fishing oysters to saving them. Residents of the Island Garden City of Samal are beginning to embrace conservation and ecotourism as a way to ensure that giant clam populations persist into the future. In Indonesia, regions of the Nibung River are closed for several months to allow populations of fish and crabs to recover.
The island country of Vanuatu has introduced bans on many single-use plastics, a shift welcomed by the its residents. Reducing our use of plastic is an important step toward reducing marine pollution and debris. Plastic debris in particular collects in ocean gyres. The Great Pacific Garbage Patch may be the most famous of the polluted ocean gyres, but they occur in all our earth’s oceans.
We also learn about the importance of preserving freshwater ecosystems. During the twentieth century, the United States witnessed a flurry of dam building for hydroelectric power. As these dams have aged, their contributions to power grids have also diminished. Read Tara Lohan’s piece about the Elwha River and Glines Cayon dam to see what environmental changes result from the decommissioning of dams.
