I’m now told that the major contribution to global warming is in fact the raising of farm animals! So we should all become vegans.David the issues you raise, seem to have no solutions, at least none that we in Exmouth can influence. What can we do about international shipping?why has our government not invested in this supposedly ‘clean coal’ what is that exactly? Instead they have mortgaged every single one of us to persuade the Chinese and French to build a new generation of nuclear power stations and nobody can accuse the green movement of inaction on that front.We can however hope to influence local development to be sustainable. A report for Greenpeace concluded that we could provide 85% of electicity from renewables by 2030 including perhaps 77GW of windpower, that seems like a significant contribution from a benign technology.
