Question

Read the following carefully and prepare a summary giving a suitable title Young marine turtles are swallowing large quantities of plastic, with ocean pollution changing habitats that were once ideal for their development into a risk, researchers have found. The impact of plastic on wildlife is a growing area of research, and studies have revealed harrowing cases of marine animals sustaining injuries r dying after ingesting such material or becoming entangled in it. One study estimated that between 4.8m and 12.7m metric Tonnes of plastic entered the world's occans in 2010 alone, while a recent review by the Australian government's science agency, CSIRO, found that animals across 80 different species, including turtles, were being killed by ingesting plastic. Now researchers studying young sea turtles, ranging from hatchlings to those with shells under 50cm in size, say the of plastic in the world's oceans means evolutionary adaptations that once helped the creatures thrive are putting them at risk. Writing in the journal Frontiers in Marine Science, researchers in the UK and Australia report how they looked for the presence of plastic in the innards of 121 sea turtles of five species green, loggerhead, olive Ridley, hawksbill and flatback. The turtles were from the Indian Ocean off the west coast of Australia, and the Pacific Ocean off the east coast of Australia, and were either stranded or caught unintentionally. The results reveal that specimen of all the species. except hawksbill turtles, of which only seven specimens were examined - were found to have plastic fragments in their gastrointestinal tract. The proportion affected was higher among turtles from the Pacific Ocean. Of the green turtles from those waters, 83% were found to contain plastic - compared with 9% from the Indian Ocean - with the material accounting for up to 0.9% of their total body mass. One green turtle specimen from the Pacific Ocean was found to contain 144 pieces of ingested plastic more than 1mm in size. Meaning: harrowing: acutely distressing or painful Innard: internal organs of person or animals​
