Which brings us neatly to a later interview this morning on Today with a man who is running a very large voluntary survey of people's faecal matter. He waxed lyrically about the importance of a varied population of microbes in the gut and the interviewer asked him how well vegetarians scored. He said that the key was as many variations in the diet as possible and by definition that meant that on average vegetarians were low average scores because they prohibit many things. He said that given the same diet, the addition of a cheese butty would be an improvement. Right on!

A couple of years ago I mentioned how atmospheric CFCs and the ozone hole were not disappearing as fast as expected and that the cause was thought to be increasing use of the chemicals in Asia. This is now confirmed. CFCs phased out in the West and supposedly banned from use in fridges, aerosols etc are being used again in Asia. A further problem is the disposal of old fridges (and their CFC content) as they are replaced with new. The CFCs can hang around for 50 years in the atmosphere and they also boost global warming....LINK

Something I don't understand about reducing carbon and pollution is the fact that even though all the evidence is that in terms of overall carbon cost burning Biomass in power stations like Drax is possibly as bad or even worse than coal burning in its overall effect. But 'burning wood' a renewable fuel seems so plausible. There are even mutterings about domestic wood burning now......
