“Merchants Of Doubt” is a documentary based off the book written by historians Naomi Oreskes and Erik Conway. The story unfolds by showing how scientists with extensive political and economic connections have ran a effective campaign over the last 4 decades to mislead the public on health and environmental issues. The documentary covers how the public's understanding has been skewed by so called ‘experts’ on pressing topics such as DDT, tobacco smoke, acid rain, and global warming.
