No border is safe

Despite their important role in conservation, marine protected areas (MPAs) are increasingly contaminated by microplastics – tiny plastic particles that are transported across borders by ocean currents.

 

Case study: Galápagos

Even in the well-protected Galápagos Islands, high levels of microplastics have been found in sensitive habitats, affecting species such as hammerhead sharks and marine iguanas.

 

Pollution without borders

Waste from distant coasts and fishing fleets is entering marine protected areas. UV radiation accelerates the breakdown of plastic and exacerbates the problem, especially in equatorial regions.

 

Science and solutions

Researchers are mapping the flow of plastic, focusing on color particle-based pollution from ships, and promoting measures such as river barriers and biodegradable alternatives.

 

Global change needed

Local initiatives are helpful, but scientists warn that only international cooperation and source measures can effectively stop microplastic pollution.
