The writing was fine, but he certainly wasn’t supporting his thesis. I was especially irritated because not all that long ago I read a book that DID support the thesis, and Pollan nowhere acknowledged that prior book. That book is “In Praise of Plants” by the French tropical botanist Francis Hallé. The book is filled with accessible science and, most importantly, a stupendous sense of humor. I highly recommend it, especially to all those who were disappointed in Pollan’s book.
