Enter the Rio+20 Global Youth Music Contest

Here's another long-winded UN name for you: United Nations Commission on Sustainable Development (Rio+20 Earth Summit). Yes, it may be difficult to craft a song whose lyrics include all that, but luckily you don't have to. All you need to do is create a song with a sustainable development theme, and if you're the winner you'll be able to attend the conference in June 2012. The conference, by the way, is in Brazil. So you'd best start plumbing your brain for words that rhyme with things like 'equity', 'biodiversity' and 'sustainability'. (Not really, but you may have noticed that, handily, 'city' rhymes with all those things if you have an unconventional singing style.) You have until February 15 to submit your masterpiece and more information is available at http://www.glocha.info/.

Effort involved: have you listened to radio lately? I'm sure you could do better than plenty of these people.
