oh dear perhaps you should try talking to some ecological or biophysical economists before making statements like that.
As the president of the Royal Society you are supposed to be a proper scientist i.e. sceptical of unfounded and unevidenced claims.
As a scientist I truely dispare of scientists like Paul Nurse and David King implying that our societial problems are purely technological. They are not, we cannot achieve sustainability through scientific innovation alone, these are socio-technological problems. There is a clear co-evolution between society and technology and we need to address norms and behaviour as well as technology. The shame is there is a great deal of scientific literature that addresses these issues.
I wish some of our "science leaders" would make a bit of effort and read up on issues they happily pontificate about for a position of seeming ignorance.
