This should’ve been required reading since the ‘70’s.
Format: Hardcover
It takes a strong writer with a very clear view ( back in the early 60’s) to make a very sciency topic into a gripping read. Ms. Carson broke down a complex scientific relationship between chemicals and the welfare of the planet and those of us who live here.. All of us, down to the microbes. This is a very logical explanation of how all living things are dependent on a clean environment, and how profiteering companies have compromised the health of all life on earth in the name of fewer weeds, attractive produce at the market, and ignoring the failures of the chemical approach that disregards integrated pest management.
I promise you that it’s not a boring textbook study.
I was a pest control advisor for many years, and had I known then what I know now I’d have trusted less in what I was trained, looking harder into the collateral damage that was created, and pushed harder, sooner, to stop the use of carbamate, organophosphates, and other “harmless” pesticides and carriers that have destroyed a multitude of environmentally sensitive and important components of a healthy ecosystem that we may not recover from in the name of profit.
Other than that, it’s light reading!

Poor formatting on kindle version
Format: Kindle
Five stars for the book, 0 stars for the formatting of this kindle version. Every word that contains a double "l", such as "all", "Stillness", "hill", etc. omits the second "l" in the word. Universal y. Kil. Al. Germ cels. It is extremely annoying, and one or more on nearly every page. Is it possible to swap this one for a kindle version with better formatting?

Intense and Informative
Format: Paperback
This is some intense and easily consumed deep reading material, compelling us to gaze uncomfortably at and into the unflattering challenges which continue to face the African-American collective "Community," and delves head-on into examining & explaining how the "HISTORICAL EXPERIENCE" of Black People in the United States, those who were the unfortunate descendants of the Trans-Atlantic African Slave Trade, has both simultaneously "Strengthened" and "Hindered" hindered life for this segment of the North American population across the Generations, to where many of its effects are still being felt even to this very Day.
This is a powerful companion to Dr. Carol Anderson's excellent book on on the Societal struggles of Blacks in America - "WHITE RAGE: The Unspoken Truth Of Our Racial Divide"
