What is the author's style in The Omnivore's Dilemma: A Natural History of Four Meals by Michael Pollan?

Michael Pollan is a journalist and sets out on the research for his book by simply wondering why the question of what to eat is so challenging for humans. As a journalist Pollan is inquisitive, and his writing reflects this questioning nature. Although he does cover all the food chains, he is, arguably, biased for the organic method of agriculture. It is clear through his writing that Pollan is against governmental control of anything and he is highly concerned about the state of the world in terms of the effects of industrialization on plants, soils, air quality, animals, and humans. Pollan's experiences as a gardener also show his propensity for natural foods.
