Overfishing is a subject we're all dimly aware of, but for those who enjoy eating our finned friends, it can be easy to forget about this troubling issue when a tasty meal is on the cards.

A new film called The End of the Line aims to wake us up to the effects of our love affair with fish as food, by revealing the impact of over-fishing on our oceans. In the film we see firsthand the effects of our changing diet on species like blue fin tuna, which are facing extinction due to Westerners' growing appetite for sushi, the impact on marine life resulting in huge overpopulation of jellyfish; and the profound implications of a future world with no fish that would bring certain mass starvation. It's enough to put you off your fish supper...

The film has been put together by a team of experts, and Stephen Fry is a bit of a fan, claiming on Twitter that he was 'staggered by its brilliance'. Read on to find out how to see a special screening of the film this Monday

It's definitely picnic weather this weekend, and in many ways there's no greener way to eat. Here are a few tips on how to ensure your al fresco adventures are as green as possible!

• Before the fun starts, make sure your guests are all well versed in appropriate litter disposal: nothing like strewn coke cans and plastic plates to ruin a nice walk in the park.

• Don't forget to bring different bags for a temporary, mobile recycling scheme - labelled if you want to be really organised! Your supermarket bags for life should do the job.

• Some collateral cutlery damage hard to avoid with larger groups, so to ensure minimal impact on the environment, consider buying the biodegradable sort like this set from Ethical Superstore.
