It’s too late to restore the ocean. Now all we can do is triage

By the Editorial Team · Monday, October 12, 2026

David Helvarg, executive director of Blue Frontier, warns that irreversible damage to marine ecosystems requires shifting focus from restoration to urgent damage control due to climate change, overfishing, pollution, and habitat loss. He stresses that protecting remaining healthy habitats and drastic emission reductions are critical to preserve ocean functions vital for human and ecological wellbeing amid ongoing political resistance to climate action.

A long-time ocean conservation advocate has expressed growing concern over the irreversible damage to marine ecosystems, underscoring the urgent need for a shift from restoration to damage control. David Helvarg, executive director of Blue Frontier and a seasoned journalist on ocean issues, reflects on decades of environmental decline and escalating threats to the world’s oceans.

Helvarg recounted a recent dive off Kawaihae on Hawaii’s Big Island, where he observed extensive coral reef loss and a sparse underwater ecosystem, attributing the degradation primarily to climate change, industrial overfishing, pollution, and coastal habitat destruction. While once optimistic about reversing these trends through policy action, emerging clean energy technologies, and public engagement, Helvarg now views the situation with diminished hope due to ongoing fossil fuel-driven climate disruption.

The warming and acidification of ocean waters, along with changes in circulation and oxygen levels, have accelerated harm to coral reefs and kelp forests, displaced fisheries, and heightened risks to coastal communities through rising sea levels and more intense storms. Helvarg points to historical environmental crises such as the aftermath of Hurricane Katrina in 2005, the 2007 Cosco Busan oil spill in San Francisco Bay, and BP’s 2010 Deepwater Horizon disaster in the Gulf of Mexico as pivotal moments that failed to prompt the necessary large-scale political change.

He also highlights persistent political and corporate resistance to effective climate action, citing efforts by the fossil fuel industry to undermine scientific consensus and the recent policy stance by the U.S. administration promoting fossil fuel extraction while opposing offshore wind and other clean energy initiatives. According to Helvarg, this approach exacerbates ocean degradation rather than mitigating it.

Given the ocean's role in absorbing a significant share of excess heat and carbon dioxide, Helvarg emphasizes that the current "buffering" capacity comes at great ecological cost. He urges a pragmatic shift toward triage—prioritizing the protection of remaining healthy marine habitats and implementing essential measures such as eliminating fossil fuel emissions, creating marine protected areas, ending destructive fishing practices, preventing pollution, and restoring coastal wetlands and reefs.

Helvarg acknowledges that restoring the ocean to its mid-20th-century state is no longer feasible, given population growth and the scale of environmental changes. Instead, he calls for sustained collective action to preserve ocean ecosystems essential to human and wildlife communities alike. Drawing on his decades of experience, he concludes that while regret and pessimism are understandable, commitment and continuous effort remain crucial to maintaining the ocean’s role in supporting life, culture, and global economies.
