'Tell him he's dreaming'

Call me cynical, but this catchprase from the 1997 Australian film The Castle came to mind in response to comment on a previous post on this site asking why more isn't done to encourage people to take big steps towards a low carbon transformation of their lives. Perhaps my cyncism, if that's what it is, is just a passing moment from reading that both 'debauchism' and 'disapora' tourism will be served by, for example, the hundreds of new jets on order from Boeing and Airbus.
