Scientists are researching underwater and have found out that turtles are going to be extinct by the end of this year. Sea turtles have been living and thriving in the world’s oceans for 150 million years, they are now in danger of extinction largely because of changes brought about by humans. So do all the best to keep them alive. Science now has definitive proof that plastic debris is killing sea turtles. Australian scientists analysed nearly 1,000 turtles found dead and washed up on beaches. Their study found that once a turtle has 14 plastic items in its gut there was a 50% likelihood that it would die.
