WhiplashII writes: According to a leading environmentalist, walking to the shops 'damages planet more than going by car'. Walking 3 miles (and the food burned to do it) releases 3.6 kg of CO2, driving only releases 0.9 kg. Other surprises: Diesel trains outpollute cars, someone who installs a "green" lightbulb undoes a year's worth of energy-saving by buying two bags of imported vegatables, and killing all our cows would do more to prevent global warming than ending all air travel.
