Chase the dream

If the contestants on ITV's The Chase are representative, we're in for a grim future. When Bradley Walsh asks them what they'd do if they won any money, the answers are depressingly similar. Fly long haul to Japan for a holiday, why not? Take a Caribbean cruise, take two cruises, four even. Drive a 3,500kg campervan across America. Lucky for the rest of us, and the planet, that most of them lose.

You dont hear the phrase 'conspicuous consumption' much these days, but it's alive and doing rather too well. Is it possible that one day personal happiness won't be measured in tonnes of carbon burned?
