Do you get the feeling a movement is growing?

We were in Selfridges today and came across this:

It’s a big installation/ad/public service announcement in the middle of London’s second most famous department store.

Its purpose is to sell Sodastream, but if that motive leads to things like this then that’s fine by us.

(By the way, we’ve had a Sodastream for months now and it’s brilliant. No fuel used to transport carbonated water and no waste. It’s also much, much cheaper. If you like fizzy water, get yourself one today.)

It comes hot on the heels of an ad we saw in Friday’s London Evening Standard for a home water dispenser that gives you cold filtered tap water in your kitchen. Like Sodastream, it was being sold on its environmental benefits.

If any of you spot any more of these nods in the right direction, let us know.
