Title: World Oceans Day 2025: Wonder : Sustaining What Sustains Us by Brent Simon

Another June 8th arrives. The calendar says World Oceans Day, but for many Caribbean communities, the ocean’s presence is now marked by thick, brown waves of sargassum invading our shorelines.

This year’s theme— Wonder: Sustaining What Sustains Us —feels less like a call and more like a wake-up alarm. And sargassum is the snooze button we keep hitting.

From Blessing to Burden

Once a natural marvel that provided shelter to marine life in the open Atlantic, sargassum seaweed has become a slow-moving ecological disaster. What used to drift in manageable quantities now arrives in record-breaking mats, blanketing beaches, clogging harbors, suffocating coral reefs, and releasing noxious hydrogen sulfide gas as it rots—turning paradise into purgatory.

In Barbados, boats are stranded. In Antigua and Barbuda, hotels battle stench and cancellations. In Dominica, fishers are watching fish flee or die. Coastal livelihoods are under siege, and clean-up costs are draining already stressed national budgets.

But sargassum isn’t just a nuisance—it’s a symptom.

The Ocean Is Out of Balance

The explosion in sargassum growth is driven by nutrient pollution (from agriculture and sewage) flowing into the ocean, combined with warming waters and altered currents. In other words: climate change plus human neglect equals crisis.

And the Caribbean is stuck in the crosscurrents. We contribute least to the problem, yet bear the brunt of it—economically, environmentally, and socially.

Sustaining What Sustains Us- this year means acknowledging this imbalance—and responding with bold, region-first solutions.

Time to Flip the Script

What if we saw sargassum not just as waste, but as opportunity?

Biofuel? Fertilizer? Construction material? Research is already underway. Let’s fund and fast-track it.

National and regional sargassum response plans? Long overdue. Coordination beats chaos.

Sargassum monitoring and early warning systems? Available. Use them before coastlines get swamped.

Coastal zone management laws and enforcement? Patchy. Strengthen them—yesterday.

And let’s be clear: cosmetic beach cleanups won’t cut it. This is a systemic issue. Until we address the upstream causes—like deforestation, agrochemical runoff, and warming waters—we’re just mopping the floor while the tap is still running.

The Caribbean Must Find Solutions

Sargassum is a foreign invader but we are the first to be affected as it makes it way from the Atlantic, through the Caribbean Sea and into the Gulf of Mexico and beyond. The ocean surrounds us, feeds us, protects us—but now it’s pushing back. We can’t wait for someone else to fix it.

This World Oceans Day, the Caribbean must awaken new depths of political will, regional unity, and blue innovation. Not out of luxury—but out of necessity.

Because if we don’t act now, the next generation won’t remember the ocean as a place of bounty and beauty—but as a burden we failed to carry.
