Sir David deserves all the respect and awards going.. his series over the years have been thought-provoking, educational and above all, showing us all how the effects of humans has had, is having and will continue to have on the world.

His clarion calls for conservation and the effects of deforestation attest to his decades-long fight for the natural world, and that world will be a poorer place when he's gon.

What a shame, then, that several countries - in particular the US & Canada - have decided not to buy the 7th and final episode of 'Frozen Planet' - the episode entitled 'On Thin Ice'.. dealing with the ongoing and accelerating effects of climate change.

Surely the TV audiences in these countries, who up until now have devoured every BBC natural history series headed by Sir David, can make up their own minds on whether this globally respected man's opinions and findings are sound, without the networks positively discriminating, and electing not to let their audiences see this programme?

I'm aware of the virilent opposition to the very idea of climate change abroad in North America, which inconveniently is the source of much of the problem, but I would have thought that, in what must be one of the most democratic continents in the world, that a programme by Sir David Attenborough is deliberately ignored?
After all, the deniers and nay-sayers can always change channels, or am I being altogether too sensible?

What about Patrick Moore?

I wouldn't argue with that.
The Frozen Planet is the most amazing nature series I've ever seen.
Mind you, I suppose that is due more to the cameraman than to Attenborough.

Sorry if above is thought to be misleading but the headline I was refering to was that which appears on the front page of the ' Huffington' , which reads,"Attenborough trumps Potter for national treasure title."

This headline typifies the press. It is no coincidence a headline like this trying to undermine Ms Rowling the day after she gave evidence in the Leveson inquiry!
