Funny thing is I got some Walkers crisps the other day that now states on the back 'since 2005 Walkers have worked with the Carbon trust to reduce our carbon emissions'. They have a neat little logo to show CO2 with an arrow in it to convince you the number is going down. That number is 75g of CO2 was used to produce that one bag of crisps. That bag of crisps weighs 37g! Jeez, we are so screwed now! there's no way I can give up crisps, we're doomed!
