Smartphones, we all use them, but how sustainable are they really. Tonnes of electronic waste is generated each year and we need to do our part in reducing it.

The United States and China contributed most to record mountains of electronic waste such as mobile phones, hair dryers and fridges in 2014 and less than a sixth ended up recycled worldwide, a UN study said.

The mountain of refrigerators, cellphones, TV sets and other electrical waste disposed of annually worldwide is forecast to grow by a third by 2017, according to a UN study released yesterday.

Indigenous people from around the world are gathering this week for a conference on climate change – a subject they claim affects them disproportionately even though they share relatively little responsibility for it.
