China has cleared 51 tonnes of trash from a scenic southern region famed for a craggy peak featured in Hollywood blockbuster Avatar, after videos went viral on social media showing ancient caves used as a rubbish dump.
The caves in a national park in Hunan province were stacked with stinking garbage up to seven or eight storeys high, leading to a build-up of sewage, videos on Chinese social media and public broadcaster CCTV showed.
