Steve Milloy, author of this book, is a Washington, DC, lobbyist who has represented just about every polluting industry imaginable, especially the tobacco industry. If you doubt this, read the book Trust Us, We're Experts! by Rampton and Stauber, who have pages on Milloy, CATO, American Council on Science and Health, and their PR campaigns to smear health and environmental concerns as 'junk science' waged by evil public interest groups and activists like Ralph Nader. Pure industry propaganda.

Add these ingredients:Flashy music, beautiful ladies, sexy dance moves, scanty clothes (no nudity), beautiful landscapes, and even some seaside hobbies... and what do you get?Wait a minute...Now add a film editor who thinks his amateurish effects are more important than the above ingredients. All the above scenes of the hobbies, the ladies, the landscapes were all spliced and edited into each other for a "strobe" effect of split second images so that you can't focus on any of it.Now what do you have?Probably a yard sale item in the 10 for a dollar bin. I may buy some of the earlier volumes to see if they're the same... wish me luck.
