"Lights Out" is a badly-written, breathless, and confusing book on the conflict between our evolutionary capabilities and post/industrial environment, from living conditions to diet. It's absolutely awful...but well-sourced, and broad in scope. I hate recommending it but if you can make it through the cringeworthy tabloid prose the second half of the book contains a decent academic bibliography.

Edit: two writers, one academic and one popular. bad combo.
