Every community has the power to protect our local waterways,

lakes and rivers that lead to the Ocean.


June 9th, 2018 was a day to Wear Blue and March for the Ocean. Thousands took action to show the government and polluting industries that we stand united to protect the waters that give us all life. We voted for the ocean! We marched to put an end to the petrochemical, plastic and other polluted runoff that is poisoning our drinking water and coastal seas and putting our health and economies at risk; we marched for clean energy - for economic, job-generating safe alternatives to offshore oil drilling and spilling; we marched for neighborhoods and communities endangered by rising seas, intensified hurricanes, historic flooding and other calamities exacerbated by carbon and other greenhouse gas pollutants. We marched in support of science that is funded, respected and uncensored and common sense solutions for our and future generations.
Together, we can build a healthy Blue Planet based on equity, justice and clean water for all. Join us in 2019!



Protect what you love. Rise with March for the Ocean to defend our coasts and ocean.

From seagulls to sea lions and everything in between, we depend on a healthy and resilient ocean. Will you march with us in 2019?
