Roger Daltrey, singer from 1970s British rock band The Who, told British newspaper The Sun in May that "the last thing the planet needs is a rock concert."
Who's really unaware about the problems caused by climate change? Presumably people who haven't watched television, listened to the radio or picked up a newspaper in the past year. I'm sure they'll hear about this though.
While looking out for the environment definitely isn't a terrible cause to champion, let's hope the next fad crusade is headed up by less politicians and rock stars.
