Going Green is a response to real AND imaginary environmental problems. Unfortunately, environmental issues are not sucker-proof. And it requires homework, scientific literacy, and well-above-average analytical abilities to evaluate some of the claims made by prominent Greenies, and by our state and federal governments.
Several months ago, I read that the Energy Star program does not actually test many of the products that get its seal of approval. A substantial part of that process is automated, and does not involve evaluations by real live people in real laboratories. If you manufacture a tenth-rate product, and hire a lawyer to do the Energy Star paperwork, you can get low-cost, misleading advertising, courtesy of Uncle Sam.
On the other hand, there are specific government standards for organic food. Notwithstanding the wild claims made by closet Marxists and paranoid Luddites, I have not seen much meaningful research suggesting that organic food is more healthful for most people, as compared with conventional food. One possible exception that comes to mind is that grass-fed beef and dairy products have higher levels of CLA than the corresponding conventional products. (CLA is a mild ant-carcinogen.)
Having Sensory Integration Dysfunction, I've gotten strange reactions--and not just allergies--to a wide range of foods and beverages, at different times. In my experience, these adverse reactions have absolutely nothing to do with the Political Correctness of the foods and beverages in question.
The short answer to your question is yes, there are lots of Green scams out there. But not all Green memes are scams. Caveat emptor applies applies as much today as at any time in the past.
