The problem is that everyone ignores potential efforts in their own way. I use the bus a lot, but on a Saturday I might drive 1 hour to a Folk event. For all the mixed efforts I can at least look to Lundun (innit?) and question the "upto" 2 hour commute and label it (truthfully) madness. And look at the Chelsea Tractors going to work.
The car industry has given us ever more economical cars and "battery &/or hybrids" that still pump out CO₂ somewhere in the chain. And then gives us gas guzzlers with ever more power (to guzzle). And cute phrases like "Self Charging Hybrids" that hide the truth.

And then there are the ever greater numbers of people who want what we have. Science and Technology will sort it, but only when it is so bad, and we won't like the results that it implies. Predictions won't tell you all! Brace yerself.

My Canadian cousins, on a visit to Europe (air miles?) commented on lack of UK efforts to re-cycle - obviously not registering the green houshold bins and maybe hidden public bins in pretty Cotswold places they "had" to visit. But they had a point, is it enough?

how do we go from here? - it requires a climate of puritanism. But like the Victorians who signed the "pledge" - it didn't close the pubs. It has to hit rock bottom, and that is a long way down.
