supermarkets

In Africa, safari-bound tourists are usually keen to bag ‘The Big five' - species which once people wanted to shoot with bullets, but are now ones we want to shoot with cameras. However, we're so keen to ‘bag’ these species, that tourists often overlook the other amazing wildlife all around them.

It's been a good week for seafood sales. The Guardian reports that supermarkets have been doing brisk business in "sustainable seafood", particularly those featured in the various Big Fish Fight shows on Channel 4.

Another tin of tuna, because we know you can't get enough of these pictures

The old saying about a can of worms, is based on the idea that once you open said can, it's impossible to get the worms back in and close it again. Who knew that was true of cans of tuna too?

But fresh from our update on some of the international branded laggards yesterday, comes some news of more developments from some of the UK retailers.

We're beginning to see the first positive results from the light bulb retailers league table we published nearly two weeks ago. Both ASDA and Morrisons have just announced they will improve their game plan and phase out those power-crazy incandescents by the end of 2010, which moves them a couple of places up the league table, leapfrogging several other retailers.

I was just about to write a piece slating Woolworths (as, after all the fuss we caused on Saturday, we still hadn't heard from them) when I got a call from Laura, one of our campaigners, to say she had a letter from them explaining what they're going to do about energy-guzzling light bulbs. I'm looking at it now and I'm sorry, but I'm still going to slate them.

It's from CEO Trevor Bish-Jones who begins by not asking for us not to stage in-store protests in future but to communicate directly with himself. So he'll be pleased about all the emails he's been getting from you (if you haven't emailed him, do it now, or you can call your local branch of Woolies and speak to the manager).

He goes on to use some well-worn arguments which I thought it would be useful to air here. Take it away, Trevor.
