New Delhi: The world’s oceans have now become plastic stocks Most of the plastic waste that accumulates in the oceans goes from the soil to the oceans. More than 14 million tonnes of plastic enter the sea every year. Most of the river-borne plastic entering the sea comes from just 10 rivers, eight of which are in Asia. China’s Yangtze River stores 1.5 million metric tonnes of plastic in the sea of plastic a year.
Plastic waste breaks down into small particles in the ocean when exposed to sunlight, wind, and waves. These particles are often smaller than one-fifth of an inch.
