There have been many books on sustainable lifestyle but nothing was as clear and elaborative as this, way to go! Beginners will fall in love with zero waste lifestyle after reading this book.
A small suggestion if you don't mind, please do include more DIYs.
For example: You have mentioned ingredients and resources to make toothpaste but feel like if you just give 2 to 3 different toothpaste recipes each of 2 sentences hardly and then ask readers to research that would have been more good.
Not only toothpastes, but shampoos, DIY gifts etc. Ensure to include literally 2 to 3 DIYs and then leave it for audience to research.
This is just a suggestion for improvement but that doesn't mean it is lacking something, there could not be any better resource than this for us.. love u sahar for such a beautiful initiative!
