The invisible waste behind our laptops and smartphones   We tend to focus on household garbage as a measure of our ecological footprints. But what about the waste and pollution that is generated to make the stuff we buy? Producing electronics involves high levels of hazardous chemicals, greenhouse gases and water drainage Most people think they know what waste is. It s the plastic they rip off their broccoli and toss in the bin.
