A recent study from the University of Las Palmas de Gran Canaria (ULPGC) reveals that the Canary Islands have become a global hotspot for microplastic pollution, affecting local marine wildlife, including dolphins, whales, and sea turtles.
Microplastics are now present in some of the most ecologically rich areas, such as the Teno-Rasca whale sanctuary. This sanctuary is home to numerous unique species, including Europe’s largest population of tropical pilot whales. The study found millions of tiny plastic particles coexisting with these animals, raising concerns about the long-term impacts on their health and the ecosystem.
Key findings from the study include:
The concentration of microplastics in certain areas of the Canary Islands is higher than in many oceanic islands.
Plastic debris accumulates in windrows, creating hazardous environments for marine life, particularly for sea turtles that feed near these areas.
At least 17 million microplastics per square kilometer were recorded in the surface waters around the islands.
The research highlights that while some marine vertebrates can expel ingested plastics, the chemicals associated with these plastics pose additional risks. The study emphasizes the need for immediate action to mitigate plastic pollution and protect marine biodiversity.
As microplastics continue to infiltrate these vital ecosystems, the researchers call for increased awareness and action to reduce plastic consumption and improve recycling efforts.
