The book is an eye opener to the lengths to which corporations and government have gone over the last several decades to hide the potential harm various environmental threats pose to the public. From smoking and second hand smoke to climate change and pollution, a few key people have misled the public for decades with funding from a variety of benign sounding organizations. The book exposes research done without invoking the scientific method, funding sources and special interest groups and corporations who benefit from the misleading information and studies that result. This book was a difficult read but an education and a cautionary tale --- making the point that people should look for the qualifications of those who are presented as experts and also that we need to look at who is backing them.
