Singapore: Turning plastic bottles into floating gardens
In Singapore, a group of volunteers are encouraging people to turn plastic bottles into mini floating gardens, known as chinampas.
It's a modern spin on an ancient farming technique originating from the Aztecs, who built artificial floating islands in lakes and found a way to grow plants and food on them.
Singapore recycles very little of its plastic waste - and some are hoping to change that.
