It's not very helpful. Why do we need to read it? Why now? How is it related to this topic?

Those answers may be obvious to someone who's already read the book. To people not familiar with the book it's a cryptic imperative.

Ahhh, fair point.

The Omnivore's Dilemma zeros in on the diminishing quality of vegetables due to some (not all) modern farming practices. I realize not everyone agrees with Michael Pollan's viewpoints, but I believe the book forces the reader to confront the food they are consuming, the system that helps deliver it to their table, and the impact on the environment and the food itself.

Thanks!

Because it’s missing context for someone who doesn’t already know about the book.
