Nurdles are small plastic pellets, typically measuring about 5 millimeters in diameter. They are used as raw materials in the production of various plastic products. These tiny pellets are often transported in bulk and can accidentally spill during shipping, leading to environmental pollution. When nurdles enter the environment, they can be harmful to marine life and ecosystems. Animals may mistake them for food, which can lead to ingestion and potential health issues. Efforts are being made to reduce nurdle spills and improve plastic waste management to protect our oceans and wildlife.
