These ocean guardians are leading the charge in protecting our seas, innovating new methods and championing sustainable practices to ensure a healthier future for our waters
Covering over 70 percent of the planet we call home, the oceans play a vital role in generating much of the oxygen we breathe and feeding more than 3 billion people. The oceans also act as a carbon sink, absorbing roughly 30 percent of the carbon dioxide released into the atmosphere from human activities.
Yet, critical issues plague our blue waters threatening to tip nature’s balance. Overfishing, plastic pollution and ocean warming are just three of the pressing concerns that need to be addressed. The High Level Panel for a Sustainable Ocean Economy—made up of world leaders—estimates that without significant action, plastic pollution will nearly triple by 2040 to 29 million metric tonnes per year.

Thankfully, dedicated conservationists and advocates are fighting to turn the tide. Beyond the United Nations’ World Oceans Day on June 8, here are 6 young leaders across Asia on the Gen.T Leaders of Tomorrow who are fighting to keep our waters clear.

She established Seastainable in 2017 to encourage young people to commit to marine conservation, giving small grants to those who are making a difference, as well as running capacity-building workshops and community activities. It has supported more than 50 projects around the world.
