Foremost, let me note that this expansive text has some ability to educate those completely unfamiliar with eco-friendly health/beauty/fashion products. Likewise, it is a lovely presentation of the more obvious products currently available (some of which are of questionable origin/quality). Those interested in educating themselves in this lifestyle can purchase this text (but a trip around the internet would prove more effective). However, if you are already invested in this lifestyle, you may find this book a rehash of everything you learned (and possibly disliked) in your first month of exploration.
For example: Oakes pushes the Burt's Bees line (found in every pharmacy/grocery-store/Wal-Mart). (And, I must admit, I LOVE their lip-balm!) But there are better choices for health/beauty products (ones which use fewer animal-based ingredients and less plastic). It may take more effort to locate these products (which is probably why Oakes elected to feature the Burt's Bees line), but you'll ultimately feel better about your choice. Moreover, if you are a lover of Sephora (as I am), check-out their organic/natural section (many of the product have biodegradable packaging! Even the lipstick tubes!)
Finally, Oakes' approach to eco-friendly fashion is a little too "boho" (bohemian/"hippie") for my taste. (Which will possibly lead many readers to resent the text ... and see it as a painful stereotype). As a professional woman, I'm not particularly interested in carrying a handbag crafted from old food cartons or tires. (Though I find the concept amusing). The text insinuates that "sophistication" and "eco-friendly" are incompatible -- simply not true. Moreover, I am equally as concerned about the products that Oakes touts ... many of which come from third-world countries at slave-wages. "Recycled" fashion that makes a person "feel good" about him/herself probably shouldn't come from the pain of others.
Sure, buy Oakes text for a cursory, mainstream introduction to the topic ... but my suggestion is to take a stroll to your local health-food store (for simple beauty products), Sephora (for more high-end products), and simply check the internet for more eco-friendly fashion (many of your favorite brand-names have eco-friendly lines (ex. C&C California has an organic line which even has organic, flower-seed sales-tags!!) You don't need this book to begin a transformation ... you only need curiosity!
