In 1992, the Texaco Oil Company left Ecuador after nearly 30 years. The next year, a lawsuit was filed against the corporation on behalf of 30,000 indigenous people, alleging that Texaco dangerously polluted their land and water. The on-going legal battle is the subject of a documentary called "Crude." As VOA's Rosanne Skirble reports, "Crude" premiered at the Sundance Film Festival in January and had its commercial release earlier this month.
