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......

See THIS for what could be good news for many victims of breast cancer. It's a better way of assessing whether intrusive chemotherapy is needed or not.

This is a along article but it's authoritative. LINK There's background at the beginning that you can skip. There are different opinions on wood versus coal and you can get different answers depending on many variable factors. Wood is renewable but it takes a long time to renew and burning it could cause a short-term spike in CO2. It might also prompt catastrophic destruction of forests around the world by loggers. As for domestic wood burning, the concerns there are to do with emission of carbon particulates and their effects on health.

What we really need is the chemical equivalent of perpetual motion, capture the carbon and bury it in the ground. Come to think nature solved that one and called it coal......

Shellfish and corals captured billions of tonnes of CO2 as CaCO3 and now we're releasing this CO2 when we produce cement in our unending quest to concrete the World's surface.

At that mention of cement, I must tell you this...
Mrs Tiz related to me today what she was told by a neighbour. A lady who lives nearby had bought a bag of ready-mix mortar. She told the neighbour that she'd added the water and mixed it all together with a stick but `it wouldn't set' (I think she meant that it wouldn't become a pastey consistency). The neighbour had a look then told the lady to put her glasses on and read the instructions again. She should have added 0.4 litres of water but she had read it as 4 litres! :surprised:
