An enormous mass of floating garbage has been found off the coast of Thailand: a 10-kilometer stream of garbage and debris brought together by wind and tide to form a continuous floating mass. Hundreds of tons of rubbish - cans, drink bottles and non-degradable plastic - are now drifting just a few kilometers off Thailand's holiday beaches and dive sites. It highlights one of the biggest threats to the world’s oceans – plastic waste. It is estimated around eight million tons of plastic trash ends up in the sea each year, killing marine life and polluting the environment. CGTN’s Martin Lowe has this report.
