Cattle ranching in the Amazon is the single biggest cause of rainforest destruction.

Back at the end of last year, while politicians were talking about the importance of forests in the run up to the Copenhagen Climate Conference, we were busy taking on the single biggest cause of rainforest destruction worldwide – the expansion of the Brazilian cattle industry.

It seemed like it was going to be a pretty tough nut to crack, so we dug in our heels and prepared for a long fight to get lasting change at the heart of the Amazon rainforest.

But sometimes events surprise you. Completely unexpectedly, within months of the campaign starting, and following thousands of Greenpeace supporters taking action, the issue was making serious progress.

For as long as I can remember, I have played a game with myself - imagining what it is like to be someone else in a different time or a different place. It's just a bit of fun and kept me entertained for hours on long train journeys before I got my laptop. Sometimes though I wonder whether I would have the courage to stand up for what I believe in if I didn't have the luxury of being here in the UK, at this moment in time.

Would I have joined the White Rose movement, students at Munich University who were executed after spreading anti-Nazi leaflets during the height of the Third Reich regime? Would I have had the courage to sit at the back of the bus like Rosa Parks did or demonstrate in the streets in Tehran following the election results?

Whenever anyone asks me what it's like to work at Greenpeace the word that always springs to mind is privileged. Not only do I feel privileged to do a job that I enjoy with equally passionate people but more importantly to be able translate my anger about the damage done to people and the natural world into concrete positive action.
