Tamsin Omond left Cambridge University with one ambition - to become the first female Archbishop of Canterbury. After reading a popular science book about climate change she had to rethink her goal. One morning she left her church office so that she might climb the roofs of Parliament to drop banners that read: No Third Runway (at Heathrow Airport). This was the beginning of a new ambition - to build a women-led environmental movement in the UK. Since that January morning three years ago she has organised (and been arrested for) a number of high profile protests, co-founded a Suffragette inspired climate action group called Climate Rush and coordinated the recent Save England's Forests campaign. She is the author of "RUSH! The Making of a Climate Activist" and is as likely to be found in the pages of Vogue as she is to be found outside Jeremy Clarkson's house leaping over a large pile of manure.
