Actress Uma Thurman has credited her two children with keeping her environmentally aware. The Kill Bill star - who co-hosted the Nobel Peace Prize concert in Oslo, Norway with actor Kevin Spacey on Tuesday (11Dec07) - admits she knows little about Earth's climate crisis, and looks to her kids to educate her. She says, "I'm very fortunate in that I have a five- and nine-year-old who are getting a much better education (in climate issues) than any of the rest of us. So I am constantly instructed on a daily basis what to do." Son Levon Roan and daughter Maya Ray are the 37-year-old's children with her ex-husband, actor Ethan Hawke.
