Surprise! Phones in Transformation

We keep on trying to find solutions to cease global warming. But has anyone thought of phones being harmful? 

The components of the phones (screens, batteries, circuits, speakers) are mass produced. They emit heat, carbon footprints and their own sort of pollution.

For a phone to be sustainable:

• It needs to have parts that can be easily replaced and repaired. 
• It needs to have a low radiation emission. 
• It needs to be made from recyclable materials. 
• It needs to be designed to last longer than typical smartphones. 

And there are some phones that fit neatly into these categories. Example: Teracube, Fairphone and Shift. 

So, are you going to become sustainable by using one of these?
