This book is written for those contemplating getting a solar panel system if they don't know enough about it yet. A good, basic understanding of what you need to know "before" diving into it is what you will learn in order to make an informed decision; especially if you are in the United States (or Canada).
There are main basic food items that we already have in our home that can be used as DIY natural cleaning solutions or what's termed as green cleaning. You just have to know which of them can be used to clean what. This includes vinegar, baking soda, salt, olive oil, and other items that are discussed in Green Cleaning 101 - DIY Natural Cleaning Solutions with Vinegar and Other Frugal Resources That You Already Have. White vinegar is the most dominant ingredient throughout.

There is more interest in self-sufficiency during this 21st century than ever before! That blatantly tells you that people are feeling the effects of the environment around them. We're not talking about "good" effects either. We're talking about chemicals in the food we eat, pollution of land, water and the air we breathe. This also includes finite natural resources becoming scarce, thus driving the cost up as demand for it continues, etc.
This book is for BEGINNERS to gardening (organically). You get all the basics including which tools to use for doing what, terminology, etc. If you are an advanced gardener, there are still things to be gleaned from it. Learning how to start an organic vegetable garden beginning with pure organic seeds, whether indoor or outdoor, is what Organic Gardening 101 -"How To" Essentials and Tips for Starting an Outdoor or Indoor Organic Vegetable Garden teaches you to do.
