I say pop stars, I haven't heard of half of these, but perhaps it's aimed at another territory. I'll leave it up to you to decide whether this will help save the planet.
P.S. You might be aware of a band called !!!, and that's commonly written as 'tck tck tck' as a guide to pronunciation, so the title of this video/campaign is a little confusing on that front. As well as all its other faults.
