Miley Cyrus the environmentalist? Don't make me weep tears of despair

Jonas Brothers and fellow Disneyites have released a song apparently urging us to do our bit. But where's the message, exactly?
I hope its message resonates with its target audience. I really do. But why do I want to crawl up into a ball and weep tears of despair after listening to the new song for Disney's Project Green (above)?
Admittedly, the "tween pop" genre is not one that I follow closely, but I know enough to recognise that Miley Cyrus and the Jonas Brothers are about as big as it gets at the moment, particularly in the US. So when they come together with their fellow Disneyites, Selena Gomez and Demi Lovato, to record a song urging us all to do our bit for the environment you could be forgiven for expecting their collective might to produce some much-needed magic (although not, perhaps, the sort that got Mickey Mouse into trouble in Fantasia).
Well, kazaam! Just a few days after its release, Send It On is already troubling the top spot on the iTunes download chart in the US. Therefore, the first hurdle of reaching hundreds of thousands of tweenagers has already been cleared effortlessly. You wouldn't really expect anything else with Miley Cyrus and the Jonas Brothers onboard.
So now let's turn to the song's message. This is where the problems begin. Where is the message, exactly? Here's a (mercifully) quick snip of the lyrics…
Just smile and the world will smile along with you That small acts of love Then the one will become two If we take the chances To change circumstances Imagine all that we could do If we…
Send it on On and on Just one hand can heal another
It's all very "Yes, We Can", and Barack Obama's election more than proves that messages of positive empowerment do work. But I fail to see how anyone listening to this will join the dots and realise that these lyrics about the power of collectivism are meant to inspire us all to get up and tackle the many environmental challenges we now face. In fact, there are no references at all to the environment to be found within the song.
In the name of research, I steeled myself and sat down and watched the video from start to end in search of these elusive environmental references. Alas, all I could find was a sofa made of, what looks like, recycled denim that all the singers sit themselves down on towards the end of the video in what appears to be some kind of subliminal reference to the opening credits of Friends.
But maybe I've invested a little too much hope in the starlets created so skillfully by the house they call "The Mouse". For a little dose of the smelling salts, let's reverse up a year and recall Miley Cyrus's last lyrical expedition into environmentalism.
Here's a sample of "Wake up America", taken from her 2008 album Breakout …
Everything I read Is 'global warming', 'going green' I don't know what all this means But it seems to be saying Wake up America
That's a little bit more like it, but it hardly fills you with confidence that it will be the next generation – all those currently nodding their heads to Miley Cyrus on their iPods – who will be the ones to lift us all out of this giant hole we managed to dig for ourselves.
But let's not give up on the kids quite yet. As part of Project Green, Disney executives have pledged to allow children decide how the company should spend $1m on environmental projects.
