Emergildo Criollo is an indigenous leader from Ecuador's Amazon rainforest. He recorded this message for oil giant Chevron's CEO John Watson: clean up your toxic contamination.  In early March 2010, Emergildo traveled from the Amazon to California, to deliver a letter appealing for clean-up, along with 325,000 petitions from supporters in more than 150 countries.
