Throughout the book, Blanke offers tips and advice for reusing and recycling items - like recycling old tennis shoes via Nike, and how you can recycled your old computer at Staples for a $10 fee. If the book had more of an eco-mindset there are tons of other resources and creative options Blanke might have included to clean and green your house, but the book is at least a good start and she does include an extended list of resources in the back for getting rid of and/or recycling your old objects.
How does this relate to saving the planet? Well, the basic idea of just slimming down, and living more simply cannot be overstated, especially in terms of not overconsuming in order to not deplete the planet of every last resource. This book might just be the kick-start motivation you need to trim out the excess in your life. We do wish she would quit using the phrase "just throw it in the trash" - which is kind of like nails on a chalkboard after awhile. In addition, if the point is to clear out the clutter of your life (and mind) then it would also be important to say that clearing out space doesn't mean that you should buy more to fill it back up - this is also important for the planet (and your sanity).
