A citizen science study has revealed alarming levels of plastic bottle pollution along the Pacific coast of Latin America. Conducted by researchers and volunteers across ten countries, the study highlights how high population density and limited recycling facilities exacerbate the problem. Bottles collected from beaches and rivers showed a mix of local and international origins, with many traced back to distant continents. The findings indicate that maritime currents play a significant role in spreading waste across borders. Researchers recommend implementing standardized bottle return systems to enhance recycling efforts and reduce ocean pollution. The study underscores the urgent need for better waste management and public education on recycling practices in the region.
