For those that don't want to read the book, essentially there is alot of misinformation out there. When testing for human toxicity of pesticides, they only test the active ingredient in the chemical mixture. Not the other additives which could be up to ~70% of the overall mixture. The additives are very nasty and we most definitely don't want them on our food.
The main focus of this book is on invasive species. By looking at who is defining invasive species and providing a plethora of facts, this book essentially posits that the "invasives" myth is a way to sell more pesticide to governments. And offers a different perspective stating that many native plants actually benefit from invasive species - invasives often grow in disturbed soil, not the native habitats.
