Have you dreamt of the Caribbean beaches? Today, it’s the sargassum that steals the spotlight.
These brown algae, once harmless, have invaded the most picturesque shores. Their nauseating smell, toxic effects, and devastating impact on tourism and health plunge the islands into a silent… but very real crisis.

Families are choking, merchants are gasping, and the sea has lost its blue hue. A zoom in on an ecological disaster that is also becoming a social emergency.


🛑 Sargassum, the brown plague of dream beaches

They arrive in waves, without warning. In Guadeloupe, in Marie-Galante, as elsewhere in the Caribbean, residents see their daily lives turned upside down: inaccessible beaches, toxic gases, loss of income… The sargassum leaves no one indifferent.


🌬️ Pollution that hits the gut… and the lungs

When they decompose, sargassum releases hydrogen sulfide, a gas that smells like rotten eggs… and irritates the eyes, throat, and skin. For the most vulnerable, it’s hell.

The consequences are manifold:

  • 😷 Respiratory problems and migraines
  • 💸 Tourists fleeing hotels
  • 🐠 Asphyxiated marine life

⚠️ Local economies at their breaking point

Tourism is collapsing in certain areas. Who wants to lay their towel on a pile of stinking algae? Hotels are recording a cascade of cancellations. Fishermen, meanwhile, see their nets clogged and their income evaporate.


🧹 In the face of chaos: cleaning, sorting, and ingenuity

Local associations are not sitting idly by. EcoPlage or Sargasse Stop organize large-scale cleanups. But the fight is tough and the resources are limited.

Some startups are trying to transform sargassum into useful products:

  • 🌿 Natural cosmetics
  • 🌱 Organic fertilizers
  • 🧴 Eco-friendly packaging

And what if this poison became a resource?


🔥 The anger rises: “We are suffocating!”

Residents are cracking. Between the stench, health risks, and feelings of abandonment, protests are multiplying. Martine, a merchant: “We can’t even open the shop!” Jean, a fisherman: “My health is deteriorating, and no one is doing anything.”

The pressure from citizens keeps rising.


🌍 Tomorrow, a united front against brown algae?

Good news: the islands are starting to communicate. The Caribbean Clean Up project aims to pool efforts between neighboring countries. Material exchanges, sharing of expertise, training: the alliance could very well reverse the trend.

The goal? Less panic, more action. Less algae, more solutions.
