Rather than being called "The Guide to Safe & Healthy, Non-Toxic Cleaning", this should have been called something like "How Everything You Breathe or Touch Is Totally Going to Make You Sick and Die Someday". I expected an introductory chapter or two on that topic, and then I expected the bulk of the book to give alternatives. But no, they went on and on about all the poisons we're living with, in our cleaning products, our personal care products, our furniture, our clothing, our food handling items, our appliances, and our very houses. What to do about all this? Well, they off-handedly gave a few recipes for natural cleaning products, but in that department they mostly referred people to "Better Basics for the Home" by Annie Berthold-Bond. But mostly the book was focused on just raising the reader's level of awareness on the issue.
I rated it as highly as I did because, although it was not the book I had expected to read, not the book I had gone looking for, it did succeed in raising my awareness. I had assumed that, living in America, Land of Regulations, the things in our everyday lives had been reasonably checked out and found to be safe to the best of our collective current knowledge. I had assumed that "Silent Spring" had ushered in a realization that chemicals can have effects beyond their primary, intended effects. I had assumed that, since we laugh at our ancestors who used arsenic and lead in their beauty regimens, we were taking care to use safer products.
Turns out I was wrong. According to this book, food products are regulated, drugs are regulated, and pesticides are regulated--but if a product is not in those categories, it's left up to the manufacturer. Which means that, in their own interests, manufacturers do enough testing to make sure it's not going to immediately make you sick, but beyond that, no one looks at it unless there's a specific lawsuit. There are zillions of different chemicals being used in the products we use, and even if someone wanted to, there is no time to test them all, let alone test the combinations that get mixed up when we use them together.
But of the chemicals (many derived from petroleum) that have been tested, there have been many negative findings, linked to cancer and malfunctionings in the immune system, hormone regulations, development, etc. We can't expect that doctors or any regulatory agency will "find these out" over the course of using them, either, because the nature of long-term low-level exposure means that it is mixed up with too many other factors, and in life (as opposed to the laboratory) we can never assign blame to one specific cause or another. But taken together, the worrisome increase in illnesses (especially in the developed world, and with some increases specifically corresponding to population segments having greater exposure to cleaning products) corresponds tidily to the increase in all these chemicals in our daily lives. And it's probably going to get worse before it gets better, because many of these chemicals are persistent, and don't break down over time (which means more and more of them are accumulating in our environment and in our bodies), or if they do break down, they sometimes change into other chemicals that sometimes have worse effects.
I, for one, plan on increasing my efforts to look for places where glass, wood, or metal might do the job instead of plastic, where water, vinegar, and hydrogen peroxide might do what pre-mixed things in bottles are hyped to do, and where an aged item might do instead of a recently manufactured one (so the worst of it has had a chance to "air out").
Another thing I didn't particularly care for in the book was the fact that they didn't address the brand name (Seventh Generation) until the very end of the book. There was no Introduction saying "We at Seventh Generation have made it our mission to. . . and to that end, we feel it's important to share with you, the consumer, this information." I kept waiting for them to spring it on me: "the only way to fight this horror is to buy good cleaning products such as Seventh Generation Ultra-Cleanser". They didn't--when there were specific alternatives mentioned in the text, they were mostly DIY recipes. Then at the very end, they rated pre-packaged alternatives, and almost half of those that made the "approved" list happened to be Seventh Generation brand. No acknowledgment at that point that there might be any bias. The company was finally introduced in "About the Authors" at the very end.
I got this book from the library, but I considered buying it for my shelf at home because it lists specific chemicals and things to look for--but then I realized I am unlikely to bother with that level of detail when I am shopping, and I should just settle for my general rules outlined above.
