PositiveThe Los Angeles Review of Books...just as the loss of certain species of small animals seemed less important before the publication of Carson’s book, a few IQ points might seem insignificant to most Americans now. That shortsightedness will change after they’ve read Washington’s book. This Shearing Fellow has written a fact-based analysis with conclusions that should absolutely animate us all ... She cuts through the crap that reeks of 400 years of racist attitudes to identify the biological consequences of 400 years of racist practice ... In her ardent call to arms, Harriet A. Washington examines the microbes that reduce intelligence in floods, hurricanes, and other everyday disasters caused by environmental hazards. Washington excavates the history of environmental racism with a clear eye on the future ... Washington’s book is a unifier, an effort to make us all realize that, \'[d]espite the tensions that have driven our perception of this problem, we will rise or fall together, not as separate ethnic groups.\' Therefore, Washington insists that we \'must topple the barriers to optimal intelligence for all Americans.\'
