I hear on the radio this morning that you and I are giving the Royal Bank of Scotland another £25bn - that's £25,000,000,000.
Or £400 each. Or the average wage of about a million people.
A couple of years ago we didn't use to talk about billions except in terms of astronomical distances or the age of the universe - real physical things that were still mind blowing. Now, hardly a day goes past without hearing that billions are going into this or that.
On the same radio programme I heard my old university chum, Simon Stuart, talking about the IUCN Red List - and how many species are heading for extinction on this badly-managed but still beautiful planet. You really wouldn't want to be an amphibian - they are having a really tough time. And about one in eight of the world's bird species is threatened with extinction.
Coming back to those £25bn of ours. I do hope that the money will be well spent. I hope it is providing funding for projects that make the world a better place and not ones which increase greenhouse gas emissions or habitat destruction. If you want the same, then please sign the RSPB's Letter to the Future and strengthen our call to politicians to protect and restore the nature on this planet.
