Alexandra Cousteau is a celebrated ocean conservationist, explorer, and masterful storyteller, carrying on a renowned family tradition of environmental advocacy. Her work is dedicated to protecting the world’s oceans, focusing on the critical intersection of policy, climate action, and community engagement. She possesses a unique ability to inspire global audiences on the weighty issues facing our water planet.

Cousteau has leveraged her platform to pioneer modern digital advocacy. She was among the first to integrate real-time social media reporting into her expeditions, turning her 2010 North American journey into National Geographic’s first "interactive expedition." By coupling traditional media and film with platforms like Facebook and Twitter, she has helped ocean conservation programs achieve record audience engagement, leading to concrete action and policy victories. She has met with heads of state, industry leaders, and NGOs worldwide to collaborate on pressing ocean issues.

Deeply motivated by the increasingly dire predictions for the marine environment, Cousteau launched OCEANS 2050 in 2018. This global program focuses on ocean afforestation—the large-scale restoration of lost coastal habitats, specifically marine forests. This mission is designed not only to provide vital habitat for marine life, reverse acidification, and sequester CO₂, but also to create wealth, meaningful jobs, and enhance food security for the world's growing population.

Her policy influence is further demonstrated by her role as a Senior Advisor to OCEANA, the largest international advocacy organization solely focused on ocean conservation. Through this work, she has been deeply involved in campaigns to curb overfishing in countries responsible for a third of the world's wild fish catch. This strategic focus aims to win measurable policy victories that increase biodiversity and secure a future for her children that is as abundant as the ocean she once knew.
