Today's "stupidity signalling" story is the mainstream media's excitement over a report that we are throwing away three billion disposable coffee cups each year. It doesn't seem to have occurred to anyone that disposable cups are disposed of on such a prodigious scale because they are made of very cheap, very abundant materials and need little energy along the way. Nor do they seem to have clocked that ceramic cups are much more expensive because they require huge amounts of energy to make.
Still, this nonsense does fill up their pages for them.
