Entity of the month
Plastic pollution is a major environmental burden, especially in the oceans where plastics remain in the marine ecosystem for long periods due to low rates of degradation [1]. It is estimated that 311 million tons of plastics are produced annually worldwide, but only a small fraction (14%) is recycled. A significant amount of these plastics is used for the manufacture of food packaging and drinking bottles [2].
