From blockbuster actors to chart‑topping musicians and royal philanthropists, celebrities are helping move ocean conservation from the sidelines to center stage. Here are seven true stories—each with a clear problem, an action, and what changed—that show what happens when fame meets follow‑through.
1. Royal spotlight: the Earthshot effect
The problem: Proven ocean solutions often struggle to scale.
The move: Prince William’s Earthshot Prize created a “Revive Our Oceans” category that injects capital and global attention into ocean solutions. Coral Vita—the 2021 winner—farms coral on land to out‑plant onto reefs, with documented growth and out‑planting milestones since the prize. The program also showcases ocean protectors (from Pristine Seas to Living Seawalls) and has continued to highlight ocean‑positive innovations at public events. The Earthshot Prize
What changed: The combination of funding, media and endorsement helps local innovations cross the “valley of death” between pilot and scale—exactly where many conservation efforts stall. The Earthshot Prize
2. Jason Momoa’s advocacy that you can’t scroll past
The problem: Single‑use plastics still dominate daily life, even as they flood watersheds and oceans.
The move: In 2022, Jason Momoa shaved his signature long hair on camera to spotlight single‑use plastic waste—an instantly viral moment that redirected attention to ocean plastic and everyday choices.
He also serves as the UNEP Advocate for Life Below Water, using that platform to push for coral protection, plastic reduction and stronger Marine Protected Areas under SDG 14. UNEP – UN Environment Programmeun.org and UN.org
What changed: The stunt earned global coverage and funneled public attention toward plastic‑free swaps. His UN role has facilitated dialogues between Pacific Island leaders and major polluters, advancing several new high‑seas protection proposals under the UN Convention on the Law of the Sea. This is an illustration of how celebrity visibility can feed into ongoing multilateral efforts rather than one‑off headlines. UNEP – UN Environment Programme
3. Adrian Grenier & Lonely Whale: from a hashtag to policy
The problem: Plastic straws had become a symbol of throwaway culture—small items with big pollution footprints.
The move: Lonely Whale, co‑founded by actor Adrian Grenier, launched the #StopSucking and Strawless in Seattle campaigns. During a single month in 2017, more than 2.3 million straws were removed from circulation across Seattle as 100+ businesses joined. The visibility helped build support for the city’s 2018 ban on plastic straws and utensils, and nudged brands toward global commitments. World Economic Forum
What changed: Soon after, Starbucks announced it would eliminate plastic straws worldwide, estimating 1 billion fewer plastic straws per year from its stores—evidence of cultural pressure translating to corporate policy.
Under his leadership, Lonely Whale established the first Ocean‑bound Plastic Supply Chain Network, linking multinational brands with waste‑collection partners in vulnerable coastal regions.
4. Pharrell Williams turns ocean plastic into apparel
The problem: Ocean‑bound plastic waste needs both cleanup and high‑volume end‑uses to avoid landfill or incineration.
The move: Pharrell Williams partnered with G‑Star RAW, Bionic Yarn, and Parley for the Oceans on the RAW for the Oceans collection—denim and apparel made with fibers from recycled ocean plastic. Early runs upcycled ~9–10 tons of plastic; subsequent seasons scaled to millions of recovered bottles. WIRED
What changed: The project helped mainstream the idea that ocean plastic can flow into desirable products—paving the way for mass‑market upcycling tie‑ups, like adidas x Parley, which produced millions of pairs of shoes incorporating ocean‑plastic materials between 2017–2020. (Product‑side demand matters: it keeps recovered plastic from becoming tomorrow’s waste.) Parley
5. Jack Johnson rewires concerts for reuse
The problem: Large events generate mountains of single‑use plastic and mixed waste.
The move: Musician Jack Johnson co‑launched the BYOBottle campaign within the Sustainable Concerts Working Group, pushing artists, venues, and festivals to provide water refill infrastructure and ditch disposables. On tour, Johnson’s team piloted reusable pint cup programs and plastic‑free shows—selling or giving away 71,000+ steel cups and avoiding 200,000+ single‑use cups across 2017–2018 dates alone. BYOBottle
What changed: BYOBottle went global as more venues added refill stations and standardized reusable options—proof that when touring riders change, entire supply chains (and fan habits) shift with them.
6. Lewis Pugh’s “Speedo diplomacy” for big ocean wins
The problem: High‑seas protections require years of negotiations and public pressure.
The move: Endurance swimmer Lewis Pugh, the UN Patron of the Oceans, has staged extreme swims—from Antarctica to the Red Sea—to keep Marine Protected Areas and the 30×30 goal in the headlines. His campaigning coincided with the 2016 agreement on the Ross Sea MPA—then the world’s largest—protecting ~1.55 million km², with about 72% designated no‑take. UNEP – UN Environment Programme
What changed: The Ross Sea deal became a touchstone for subsequent high‑seas protection efforts and shows how persistent, media‑savvy advocacy can help nudge complex diplomacy over the line. pew.org
7. Leonardo DiCaprio’s Philanthropy
The problem: Only a small share of the ocean is fully protected, and many marine ecosystems are under pressure from overfishing and habitat loss.
The move: At the U.S. State Department’s Our Ocean event, Leonardo DiCaprio pledged $7 million for ocean conservation—prioritizing new and expanded marine reserves—after previously granting $3 million to Oceana to bolster fisheries reforms. TIME and Oceana
What changed: DiCaprio’s targeted philanthropy helped accelerate campaigns for marine protections and fisheries transparency—an example of celebrity funding that complements policy work rather than replacing it. (The lesson: when donations align with science‑based campaigns, they can unlock outsized impact.)
What these stories tell us
Visibility multiplies impact when it’s tethered to credible partners (UN bodies, established NGOs, science‑led projects).
Behavior change + policy change beat either alone: hashtags moved straws off counters, while cities and companies locked in durable shifts.
Supply chains matter: turning recovered plastic into products at scale keeps momentum (and materials) moving in the right direction.
Moments drive movements: viral gestures (a shaved head, a polar swim) can open doors for long‑term wins like MPAs and global grants.
If you’re inspired—here’s how to plug in
- Pick a lane: reduce plastics (refill culture), back marine protections (MPA campaigns), or support reef and kelp restoration.
- Back doers, not just talkers: donate to groups with field programs and policy track records and check for transparent reporting.
- Use SaveOCEAN platform : Join the SaveOCEAN community as bigger community higher impact in restoring our Ocean. Lets make an impact together!
Celebrities don’t save the ocean alone. But at their best, they redirect the spotlight—and the funding and momentum that come with it—onto the scientists, communities and policies that do.
When star power is paired with staying power, waves become tides.
