Capacity for Work in the Tropics Book

I'm not sure I can take seriously and finish a book that includes, on its first page, the following statement: "Easy food, like easy sex, leads us down a path to waste and destruction of ourselves and the planet we live on." The author doesn't bother, in that preface to the second edition, to explain just what "easy food" or "easy sex" might mean, or why they (particularly the second) necessarily lead to "destruction," nor does the food=sex construction of the book seem particularly necessary for a discussion of food and disease. I'll give this one a try, as I usually like discussions of this and related topics, but I sincerely hope that the quality improves in the main body of the text.

Note: after reading this a bit more, it's fairly interesting, but the language, author's weird perspectives, and constructions continue to get in the way of it being a really well-done book.
