On Saturday June 9, 2018, World Oceans Day weekend and the beginning of the 2018 hurricane season, the March for the Ocean (M4O) campaign will mount mass marches, flotillas and rallies in our nation’s capital and around the country. People will be mobilizing to stop reckless offshore oil drilling being pursued by the Trump administration and to promote job-generating clean energy, to call for large-scale reduction in plastic waste that is killing ocean wildlife and to promote protection and restoration of our coastlines in the face of rising seas and intensified hurricanes like last year’s Harvey, Irma and Maria.
