“World Water Day” is celebrated on 22 March to highlight the importance of fresh water. Plastic pollution is among the biggest environmental threats to the oceans. Plastic items remain intact thousands of years, and they just break down into smaller pieces. Tiny pieces of plastic (5 mm or smaller) are named microplastics. They are usually made of polyethylene, polypropylene, polyethylene terephthalate, or nylon.
Microplastics have disastrous consequences for marine life and health. Fishes and other aquatic animals eat microplastics, which cause them health problems and finally die. Microplastics can also enter our food chain through the bodies of fishes we eat. Effects of microplastics on human body are still unknown, and scientists are investigating their health impacts.
