Jeff Hansen has led Sea Shepherd's global operations for over two decades. Sea Shepherd's direct action campaigns — confronting illegal whaling, monitoring marine protected areas, intercepting illegal fishing operations — have shaped public awareness of marine conservation issues at a scale few other organisations have managed.

KeepCup has partnered with Sea Shepherd over multiple years. The relationship reflects shared values around ocean health, plastic pollution and the connection between consumer behaviour and marine ecosystems. We sat down with Jeff to talk about where the work is, what's changed, and what households can do.

On the State of the Oceans

Jeff is direct about the trajectory. The oceans are in worse condition than most people realise. Marine heatwaves are bleaching coral systems faster than they can recover. Plastic pollution accumulates in gyres, fragments into microplastics, enters food chains. Industrial fishing continues to deplete fisheries faster than they recover.

At the same time, he sees real progress. Marine protected areas have grown substantially over the past two decades. Specific fisheries have rebuilt under sustained management. Public consciousness of ocean health has increased measurably. The work is far from done, but the trajectory in some areas has reversed.

On Direct Action

Sea Shepherd's reputation for direct action has earned both supporters and critics. Jeff's framing: where governments fail to enforce existing international laws, civil society organisations have a role in surfacing the violations and creating accountability.

The campaigns aren't activism for its own sake — they're documentation and enforcement support where the formal enforcement mechanisms have failed. The Antarctic whaling campaigns, the West African illegal fishing operations, the marine protected area monitoring — each had specific objectives tied to existing legal frameworks.

On Plastic Pollution

Plastic in oceans is the issue Jeff sees as most consumer-actionable. Industrial fishing pollution requires industry change. Coral bleaching requires climate policy. Plastic pollution — while it has industrial sources — has substantial household contribution.

The household plastic stream that ends up in oceans is dominated by single-use packaging, bottles, bags and small consumer items. Reduction at the household level scales because the source is distributed. The disposable coffee cup is on this list. So is bottled water, single-use straws, plastic bags, takeaway containers.

Reusable alternatives reduce the source. KeepCup products are tested to 1,000 uses, replacing thousands of single-use items across a product's life. The maths is simple and the connection to marine plastic pollution is direct.

On What Households Should Do

Jeff's practical advice for households who want to support marine conservation:

  1. Reduce single-use plastic. Permanent carry of reusable cup, bottle and bowl. The single highest-leverage household action on marine plastic.
  2. Eat sustainably-sourced seafood, or less seafood. Industrial fishing pressure is one of the larger drivers of marine ecosystem decline. MSC certification helps; eating less helps more.
  3. Support marine conservation organisations. Sea Shepherd, the Marine Conservation Society, WWF UK. Direct giving funds the work that creates pressure for marine protection.
  4. Vote for marine protection. Marine protected areas and fisheries management are politically decided. Sustained voter pressure shifts outcomes.
  5. Reduce climate emissions. Marine heatwaves and ocean acidification are climate-driven. Climate action is marine action.

On KeepCup

Jeff's view of the KeepCup partnership: useful business support for the work, and a useful demonstration of how consumer brands can engage with marine conservation without overclaiming. "You're not solving the ocean plastic crisis by selling reusable cups. But you're reducing the household contribution at scale, supporting organisations doing the systemic work, and showing that businesses can operate without contributing to the problem. That's a meaningful position to take."

On the Next Decade

Jeff is cautiously optimistic about the next ten years for marine conservation. The science is clear, the public awareness has grown, the technology for monitoring and enforcement has matured. What's missing, as in most environmental categories, is sufficient political commitment to translate the consensus into action.

The role of civil society organisations — Sea Shepherd among many others — is to keep the pressure on governments and industries to act. The role of consumer brands is to operate in ways that don't compound the problem. The role of households is to vote, donate, and reduce their own contribution.

None of these is sufficient on its own. All of them are necessary in combination.

FAQs

Who is Jeff Hansen?

Jeff Hansen has led Sea Shepherd's global operations for over two decades. Sea Shepherd is a marine conservation organisation known for direct action campaigns against illegal whaling, fishing and marine protected area violations.

What's the biggest threat to ocean health?

Multiple connected threats: climate-driven marine heatwaves, plastic pollution, industrial fishing pressure, habitat loss. They compound rather than acting independently.

What can households do for marine conservation?

Reduce single-use plastic through permanent carry of reusables, eat sustainably-sourced seafood or less seafood, support marine conservation organisations, vote for marine protection, and reduce climate emissions.

How does KeepCup support Sea Shepherd?

KeepCup partners with Sea Shepherd over multiple years through donations, awareness collaborations and shared advocacy on plastic pollution and ocean health.
