Ok, this technically isn't a novel. No, the Green Guide is just that, a great guide for ways you can make your home greener. It is written by the editors of the magazine, Green Guide and the forward is written by Meryl Streep, which seems appropriate since she is one of the founding members of said magazine.
The Green Guide has tips about which types of cleaners to use in your house. There are great ideas for cleaning the bathroom, the kitchen or even your dirty laundry. There are tips about food, buying locally, etc. They recommend going veg, but if you eat meat, they give advice about which is the safest to eat and where to get it.
There are so many more tips in this great book, I don't even know where to start, other than to recommend that you check this book out and use their tips! Everything we can do to be green is a great choice
