A replica of Auguste Rodin's famous sculpture The Thinker is being slowly submerged in plastic rubbish outside the United Nations headquarters in Geneva as countries gather to finalize a global treaty on plastic pollution. Canadian artist and activist Benjamin Von Wong created the 6-metre-tall artwork, entitled The Thinker's Burden, to highlight the health impacts of plastic pollution on future generations. Over 400 million tonnes of plastic are produced globally each year, with only nine per cent being recycled, while nearly half ends up in landfills or incinerated.
