Environmental activist Erin Brockovich became associated with the issue of polluted water after the film made in 2000, 'Erin Brockovich', for which Julia Roberts won an Oscar. Ten years later, the 51-year-old is still fighting and still going strong. 　　At the Berlin Film Festival, she introduced the latest two movie projects she is involved with: 'Last Call At The Oasis,' which explains the vital role water plays in our lives and 'Breathing Lessons: The Life and Work of Mark O'Brien' to show the world why water is the most important and most underestimated resource on our planet. 　　"We don't think about water and we do take it for granted because we turn on a tap and there it is. And maybe we take it for granted because outside of seeing it in our tap we don't really really understand water underneath us." 　　With Academy Award-winning director Jessica Yu, 'Last Call At The Oasis' exposes the defects in the current system, shows communities already struggling with its ill-effects and presents a convincing argument for why the global water crisis will be the central issue facing our world this century. 　　"I do believe people realise without water we are doomed. So they don't want to think about it and they just take it for granted," 　　"But we got some water issues coming up. Water will be a commodity someday and we are going to trade it like oil and it shouldn't be that way. The time has come where we are going to start thinking about water and the importance of water. Even though we already know it, we don't know it. And I am hope that this film will enlighten everybody." 　　Brockovich came to prominence investigating the prevalence of cancer cases in Hinkley. The movie focused on the advocate's work as a paralegal with residents of Hinkley. In that case, 660 Hinkley residents sued the utility PG&E for damages from groundwater contaminated with toxic chemicals. The plaintiffs received a 333 million-US-dollar settlement in 1997.
