World Ocean Day highlights alarming progress of plastic waste in seas

Annually, roughly 400 million tonnes of plastic products are manufactured globally, with almost half utilised for single-use objects similar to purchasing baggage, cups, and packaging supplies. It is estimated that 8 million to 10 million tonnes of these plastics end up in the ocean annually, covering an area of eleven,000 sq. kilometres when flattened to the thickness of a plastic bag. To highlight the significance of the ocean and encourage its sustainable use and preservation, the United Nations has designated June eight as World Ocean Day.
Plastic constitutes the majority of ocean litter, accounting for 80% of marine pollution. Most ocean-bound plastics result from improper waste disposal systems that launch rubbish into rivers and streams. Additionally, discarded fishing nets and marine tools contribute to the problem. Microplastics, measuring less than 5mm in length, are a major environmental concern as they can be ingested by marine life, probably inflicting hurt to both animals and humans. It is estimated that between 50 trillion and 75 trillion microplastic items are presently in the ocean.
Limited analysis on the health effects of microplastic consumption by humans suggests that these particles can accumulate in organs such as the liver, kidneys, and intestines. There are concerns that microplastics may doubtlessly cause inflammation, oxidative stress, and cellular harm. Erica Cirino, a science writer and author, emphasised that plastic particles comprise toxic chemical compounds known to interfere with human and animal hormones, potentially resulting in harmful results over time.
Spoiler examine revealed in Science Advances revealed that 80% of all plastics discovered in the ocean originate from Asia. The Philippines contributes greater than a third (36.4%) of all ocean plastic waste, followed by India (12.9%), Malaysia (7.5%), China (7.2%), and Indonesia (5.8%). These figures don’t include waste exported overseas, which can have a better threat of getting into the ocean..
