Thanks for the link, we usually catch on to what's going on in California about 10 years later so let's see what happens... The UK missed out on a big chance to reduce our consumption of bags a couple of years ago by introducing a tax so each bag would cost 10p, Aldi and places like that have always charged about 3p per bag. But the government did not take this opportunity, unlike the Republic of Ireland so we continue to drown in a sea of plastic.
Most supermarkets have what they call a "bag for life" which is a big sturdy plastic bag designed to be used many times - often with the proceeds of the purchase going to charity. Also Tesco, the Uk's largest supermarket, gives "green points" on the loyalty card when customers reuse bags or use another method of transporting their groceries. It's just a ploy to get the green pound but it's better than a kick in the face.
It is becoming very fashionable to be "green" over here though, which is good in some senses but I think it also alienates some people as it's seen as something that people with money do and it's too expensive for people on low income to achieve (the article below mentions the hype and excitement about a particular shopping bag being sported by all the so-called celebrities).
Below is a link to an article in yesterday's paper, which talks about the impact our (British) use of plastic bags has on China - where the bags are manufactured initially and where they return for "recycling". It's a shame the website doesn't show all the pictures that appeared in the paper as some people are using old packaging to make some AMAZING reusable bags
