Mr Potato Head makes an appearance in Amsterdam

It sounds like something that would have appeared on the late, lamented Eurotrash but giant potatoes have been spotted recently cycling through the Netherlands. However, it isn't an offbeat continental cultural outing, but a reminder to the Dutch public about the importance of organic farming and the perils of GM technology.

Remember the palm oil tanker which the Esperanza prevented from docking in Indonesia last month? That same tanker - the Isola Corallo - arrived in European waters on Christmas Eve en route to Rotterdam, and was met by a group of Greenpeace activists who painted 'Forest Crime' along its hull.

I was on board the Esperanza during that first Indonesian action against the Corallo and it's brilliant to see this tanker - which is carrying 29,000 tonnes of palm oil belonging to Sinar Mas, Indonesia's largest producer - becoming the centre of attention once more here in Europe. It draws a thick line across the globe between the causes of deforestation in Indonesia and demand for products like palm oil on this side of the world.

Two Greenpeace ships - one of them the Rainbow Warrior - have been impounded and their captains and 90 others arrested after three days of nonviolent direct actions in the Netherlands.

Some of the 100 volunteers occupying the construction site of a new E.on coal plant in Rotterdam.

I'll start at the beginning. On Friday evening, nearly 100 Greenpeace volunteers pitched tents next to the construction site of a new E.on coal plant in Rotterdam (one of eight E.on plans to build in Europe), to bear witness to the unfolding climate disaster.

At first light on Saturday, they moved onto the site and occupied it, stopping construction for 10 hours before all being arrested.

Over at our international office in Amsterdam, the web team have just published the June edition of their monthly round-up of images from the Greenpeace world. Being signed up to far too many internal email groups, I get to hear about what other offices are up to, but there's nothing quite like a striking image to make events in Bali or Belgium come alive.
