5 Tamsin Omond, 24, campaigner

Omond is gorgeous, intelligent and committed: the founder of Climate Rush, she was arrested last year after scaling the Palace of Westminster in protest at Heathrow expansion. She also dumped manure on Jeremy Clarkson's lawn in answer to his comments on emissions. She says: It's exciting to feel you have some power over your future. Fellow greenies adore her. Mark Anslow, editor of theecologist.org, says, Tamsin's got guts, looks and a first from Cambridge. Would you argue with her?
