A study by the International Union for Conservation of Nature (IUCN) estimates that microplastics make up 15% to 31% of all oceanic plastic pollution. Notably, the majority of microplastics in the oceans are secondary, originating from the breakdown of larger items like plastic bottles and fishing nets.
