<p>World's oceans have more than 171 trillion pieces of plastic, a new study said, citing a "rapid and unprecedented" increase in plastic pollution in the oceans.&nbsp;</p>

<p>A team of international scientists analysed the samples collected over the&nbsp;course of four decades – between 1979 and 2019 – from the Antlantic, Pacific and Indian oceans as well as the Mediterranean Sea.&nbsp;</p>

<p>"Today's global abundance is estimated at approximately 82-358 trillion plastic particles weighing 1.1-4.9 million tonnes. We observed no clear detectable trend until 1990, a fluctuating but stagnant trend from then until 2005, and a rapid increase until the present," the study, published on Wednesday in the journal PLOS ONE, read. &nbsp;</p>

<h2><strong>Oceans' plastic waste crisis: What lies next?</strong></h2>

<p>Scientists warned that the rate at which plastics enter the oceans could increase by around 2.6 times between now and 2040 without immediate intervention. "This observed acceleration of plastic densities in the world's oceans, also reported for beaches around the globe, demands urgent international policy interventions," they wrote.</p>

<p>Lisa Erdle, director of research and innovation at the 5 Gyres Institute and an author of the report, pointed out that only 9 per cent of global plastics are recycled each year. She said that once plastic gets into the ocean, it doesn't decompose but breaks down into tiny pieces. "These particles then are really not easily cleaned up, we're stuck with them," she told CNN.&nbsp;</p>

<p>"The ocean is a complex place. There are lots of ocean currents, there are changes over time due to weather and due to conditions on the ground," Erdle said.</p>
