In Laudato Si’, Pope Francis highlights the oceans as integral to our threatened common home and stresses the need for more effective ocean governance. Theologians can help to meet that need. By turning their attention to the UN Convention on the Law of the Sea (UNCLOS) and its further development, and by practicing “ocean empathy,” they can join ocean scientists, NGOs, international lawyers, and others in caring for the oceans by shoring up the law of the sea.
