end of the line

Dramatic title perhaps, but maybe not quite so far-fetched. Here in sunny Sundance, one of the questions that has been coming up repeatedly at showings of the End Of The Line movie is, "What about climate change?", assuming rightly that a warming planet will have implications for our fish populations too. Well my practised response to this before I got here was simply that the effects of climate change make all of the issues of rapacious overfishing all the more important. They make the need for precaution when it comes to fishing, and the need for fully protected areas essential.

So, what's the movie we're here at Sundance with about? Well, it's an adaptation of Charles Clover's brilliant book on overfishing, The End Of The Line, which is an evocative and shocking portrayal of what we have done and are doing to our oceans – just to put seafood on our plates.

I'm writing this from Utah, a landlocked state in the US, which hosts the Sundance Film Festival each year. Sundance is known as the place for new independent films, and we're here to support a great new documentary movie called 'End of the Line', based on former Daily Telegraph environment correspondent Charles Clover's book about what overfishing is doing to our oceans.
