Since 1985, Chevron has produced numerous television and print ads in its &ldquo;People Do&rdquo; advertising campaign. They have taken numerous actions to preserve and protect our natural environment. Ad copy reads: &ldquo;<em>Do People Care about the Environment?</em>&rdquo; &ldquo;<em>People Do</em>.&rdquo; Advocacy groups have questioned whether Chevron&rsquo;s &ldquo;People Do&rdquo; message misrepresents what they are advertising because it was compelled by court action, not altruism. The oil company situated in San Francisco, has been involved in and has lost numerous court cases&mdash;from being sued by workers in their oil refineries due to poor health conditions, to The San Francisco Public Utilities Commission (PUC) filing a lawsuit against them to force them to move a pipeline for fear that it would split in an earthquake and contaminate drinking water for the 2.5 million Bay Area residents. Research conducted has shown that the ads have had a positive impact and have resulted in increased sales of Chevron gasoline.
