Good Causes

Blue Marine Foundation

Blue Marine’s mission is to see at least 30% of the world’s ocean under effective protection by 2030 and the other 70% managed in a responsible way.

Blue Marine is filling a niche in the NGO world, enabling marine conservation to happen fast and effectively. What differentiates Blue Marine is that we are well connected and determined; we seize opportunities as they arise and get things done. We forge new partnerships and challenge the status quo.

Blue Marine works using a combination of top-down intervention to improve governance of our seas and bottom-up project delivery to help local communities who are at the front line of ocean conservation.

Our key strategic interventions are as follows:

  • Securing marine protected areas to ensure the protection of at least 30% of the ocean by 2030.
  • Developing models of sustainable fishing proving that low-impact fishing benefits marine life, local fishers and communities.
  • Restoring marine habitats to revive and protect vulnerable and threatened species and to sequester carbon.
  • Tackling unsustainable fishing by highlighting poor practice and developing solutions.
  • Connecting people with the sea and enhancing ocean understanding across generations.
