Decades of commercial mountaineering have turned Mount Everest into the world's highest rubbish dump as an increasing number of climbers pay little attention to the ugly footprint they leave behind.
Fluorescent tents, discarded climbing equipment, empty gas canisters and even human excrement litter the route to the summit of the 8,848-metre (29,029-foot) peak.
Melting glaciers caused by global warming are exposing trash that has accumulated on the mountain since Edmund Hillary and Tenzing Norgay made the first successful summit 65 years ago.

Antarctic Ice Melting Faster Than Ever
Satellites monitoring the state of the White Continent indicate some 200 billion tonnes a year are now being lost to the ocean as a result of melting.
This is pushing up global sea levels by 0.6mm annually - a three-fold increase since 2012 when the last such assessment was undertaken.
According to researchers, the losses are occurring predominantly in the West of the continent, where warm waters are getting under and melting the fronts of glaciers that terminate in the ocean.

Oldest Footprints Found in China
The oldest known footprints left by an animal have been uncovered in southern China.
The identity of the creature that made the 546-million-year-old tracks is still unknown, but they come from the period when the earliest animals are thought to have evolved.
It is unclear whether the creature had two legs or several. But they say the tracks probably belong to a bilaterian.

Plastic and Traces of Hazardous Chemicals in Antarctica
According to a new study, plastic and traces of hazardous chemicals have been found in Antarctica, one of the world's last great wildernesses.
Researchers had taken water and snow samples from remote areas of the continent earlier this year.
These have now been analysed and researchers have confirmed the majority contained persistent hazardous chemicals or microplastics.
