It's reckoned that more than a fifth of the world's greenhouse gas emissions result directly from deforestation.
The rainforests of Indonesia, for example, along with the carbon rich peat soils they grow on, form one of the largest natural carbon stores on the planet. They are a vital defence system against climate change.
Yet the rate at which Indonesia's rainforests are being destroyed makes it the third largest climate polluter after the US and China.
But there is no workable rainforest protection plan on the table ahead of global climate talks due to take place in Copenhagen in December.
I hate to admit this when it happens, but, not for the first time, I find myself in agreement with Prince Charles, who said:
'If we lose the battle against tropical deforestation, we lose the battle against climate change.'
Of course, the biggest single driver of deforestation isn't the western desire for wood, it's our desire for meat and processed foods containing palm oil.
Perhaps the best way to save the planet is to stop banging on about flying all the time and just eat a few less meat and dairy products.
Oh blimey, I'm agreeing with Lord Nicholas Stern now.
