I would encourage everyone to get to your local viewing and then to get involved with the campaign. It really is very simple. Start by visiting the website. Then follow these three easy steps:

1. Ask before you buy: Only eat sustainable fish and encourage local restaurants and shops to only stock sustainable fish.
2. Tell politicians: Politicians have a duty to protect world resources on behalf of its citizens. This means listening to the science and cutting fishing fleets to a level which will allow fish stocks to replenish.
3. Join the campaign for marine protected areas and responsible fishing methods.

So as a first step I've written to the three main political parties to find out what they plan on doing to protect the world's fishing crisis. Below is a copy of the email and I'll be posting replies as they come in.

To whom it may concern

Hopefully you will have had the chance to view the excellently shot and thought provoking film “The End of the Line” by Charles Clover and directed by Rupert Murray.

Since 2002, overfishing has been recognised as one of the world's most immediate environmental issues. Since peaking in 1989 global catches of wild fish has been in decline. So severe is this problem that according to data from the United Nations' Food and Agriculture Organisation (UN FAO) 75 per cent of wild fish stocks are now either fully-exploited or overfished. He latest UN FAO figures due out later this year are likely to see this percentage rise.

In UK waters, stocks of palatable fish, such as cod, have been reduced to less than 10 per cent of what they were 100 years ago. This compares with a global average of 25 per cent of stocks actively overfished. The problem in Europe is that some 50 per cent of the quotas set by politicians are higher than scientists say are sustainable.

The EU was instrumental in arguing for a quota of 22,000 tons of valuable bluefin tuna for next year at a meeting of the International Commission for the Conservation of Atlantic Tunas in Marrakech in November 2008, even though scientists recommended a quota of only 15,000 tons to avert stock collapse.

Ensuring the preservation of fish stocks is essential if we want future generations to enjoy this precious resource, as well as maintaining the livelihood of fishing communities.

“The End of the Line” encourages world citizens to take action by following three simple steps:

• Ask before you buy: Only eat sustainable fish and encourage local restaurants and shops to only stock sustainable fish

• Tell politicians: Politicians have a duty to protect world resources on behalf of its citizens. This means listening to the science and cutting fishing fleets to a level which will allow fish stocks to replenish.

• Join the campaign for marine protected areas and responsible fishing methods.

Whilst consumer action has the power to influence the restaurant and retail markets, Government action is vital to ensuring that the UK and other countries fulfill their obligations to create sufficient marine protected areas and to control fishing fleets and quotas in a dynamic and effective manner.

I would be very interested to hear about your plans for addressing this fisheries crisis and ensuring the sustainable regeneration of much depleted fish stocks.
