June 9, 2017 — As we mark World Oceans Day today, it is safe to say that of all the threats facing the world’s oceans in the 21st Century, the most tangible (and visible) of these is pollution. Televised images of oil spills in a once-pristine location have become the very definition of environmental disaster, while firsthand encounters with plastics and debris on a beach or floating offshore serve to remind us that no corner of the earth is completely free of human-produced refuse.
Pollution is also a major topic of discussion at this week’s United Nations Ocean Conference in New York City. The event brings together governmental leaders, conservationists, scientists, and others from all corners of the globe to focus on the ocean, its future, and sustainable development.
The discussions include efforts to conserve the world’s oceans, seas, and marine resources while minimizing threats such as climate change, overfishing, and a frightening array of pollutants ranging from solid waste runoff, hazardous chemicals, wastewater, and plastics that all flow seaward from our cities, farms, and coastal dwellings.
Some UN delegates are also focusing on another kind of pollution, one that is invisible and temporary but devastating to many marine animals: noise. Noise pollution has to be recognized as a threat to whales, dolphins, and other species, and was the focus of a specific workshop at the UN conference that my colleagues and I at Wildlife Conservation Society (WCS) organized with a number of partners last February.
Whales, which live in and migrate between marine habitats (some with considerable levels of maritime transport and other industrial activities), are particularly at risk from noise. These underwater blasts can disrupt behaviors and prevent these marine mammals from finding food and communicating with one another.
