Slideshows

If you're on London's South Bank over the next few weeks, watch out for a new open air exhibition featuring the work of regular Greenpeace photographer Jiri Rezac. He's been to the tar sands works in Canada and the images he's brought back clearly show the extent of the devastation caused by this insane venture to both the environment and local populations.

The slideshow above is just a taste of Jiri's work featured in the exhibition which you can see near City Hall by Tower Bridge until 14 October. It will then be touring around the UK - details are still to be confirmed but check the Tarnished Earth website for updates. 

Glastonbury is the big fixture in our festival calendar but throughout the summer our events crew are setting up shop at other big country bashes. They're getting people involved with our campaign to save the rainforests (see our new forest defenders making monkeys of themselves in the slideshow above) as well as providing plenty of activities to provide an alternative to the music stages.

Latitude and Womad have been and gone, but this weekend it's their first visit to the Big Chill. If you're heading that way look out for the Banksy backdrop where you can put yourself in the picture and declare your support, like hundreds of other people have already done.

With fake oil actions spilling out all over the place, it's high time someone did some skill sharing. Step up our international office with their "activist recipe for fake oil".

Basically, you mix up some molasses with some corn oil, corn starch, chocolate powder and some flour and away you go (well, there's a bit more to it than that - full recipe here).

As climate change causes the Arctic sea ice to recede, our ship Esperanza has sailed north of Svalbard to survey the poorly understood Arctic Ocean seabed. On the surface, the crew are observing and recording the diverse wildlife that has adapted to survive in this unique and harsh environment. Beneath the waves we are using a remote operated vehicle built and operated by top cameraman Gavin Newman to record the life on the sea bed in fine detail.

Greenpeace is calling for the area of the Arctic Ocean historically protected year round by sea ice to be closed to all industrial activity, including destructive fishing. Read more about the Arctic Under Pressure expedition.
