The whole concept of bottled water being sold and bought by gullible twats in areas where perfectly drinkable stuff comes out of the tap is symptomatic of the rank hypocrisy that infects the whole green lobby - "you can't do what I disapprove of but no matter how wasteful my habits are, they don't matter".
There is a fair point here but it doesn't affect the argument about whether or not certain activities, such as flying when there are viable alternatives, should be encouraged.
Of course there are a multitude of decisions that everyone of us makes every day which have an environmental impact. Many people concentrate on getting certain decisions right but fail to take action in other areas. You can call that hypocrisy but it's better than doing nothing at all.
As regards the Evian bottles ... actually I happen to agree that it's crazy to pay for water from abroad when it comes out of the tap for free. But isn't it worth getting this little extravagence in proportion?
Would you care to give me some figures which compare the carbon footprint of drinking, say, five bottles of Evian a week, with travelling 3-4 sectors by plane every week?
Here's my very crude estimation:
2.5 liters water = 2.5 kilograms x 500 miles = 1250 kg-miles
1 x cobbles = 85kg x (4 x 400-mile flights) = 136,000 kg-miles
Assuming that densely packed evian bottles travelling by diesel lorry use about 10 times less fuel per kg than humans transported by plane, I'm going to multiply your kg-miles by ten to give 1,360,000.
So it could be estimated that the impact of your activities might be in the region of 1,000 times greater than the evian drinkers.
Or to put it another way, you'd have to drink 5 thousand bottles of evian to match the impact of your weekly flying routine.
So even the Evian drinkers are perfectly justified in pointing their fingers at the serial aviators without risk of "rank hypocrisy".
