They may well be but it doesn't take much to see how many bottles of
water ther are in one supermarket then multply that by the number of

for being environmentally unfriendly but when it comes to condeming
trendy bottle water drinkers it is suddenly ok.

Given that, on occasions, I do all three of the above (with the "air
travel" one ranking quite high at the moment, though the car driving
quite low, as I'm currently flying twice weekly and spending Mon-Fri in
