Agriculture (also called farming or husbandry) is the cultivation of animals, plants, fungi, and other life forms for food, fiber, and other products used to sustain life. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization. The study of agriculture is known as agricultural science. Agriculture generally speaking refers to human activities, although it is also observed in certain species of ant and termite.

The history of agriculture dates back thousands of years, and its development has been driven and defined by greatly different climates, cultures, and technologies. However, all farming generally relies on techniques to expand and maintain the lands suitable for raising domesticated species. For plants, this usually requires some form of irrigation, although there are methods of dryland farming; pastoral herding on rangeland is still the most common means of raising livestock. In the developed world, industrial agriculture based on large-scale monoculture has become the dominant system of modern farming, although there is growing support for sustainable agriculture (e.g. permaculture or organic agriculture).

Michael Pollan (born February 6, 1955)^{[citation needed]} is an American author, journalist, activist, and professor of journalism at the UC Berkeley Graduate School of Journalism. A 2006 New York Times book review describes him as a "liberal foodie intellectual."

Pollan was born on Long Island, New York to author and financial consultant Stephen Pollan and columnist Corky Pollan. Pollan received a B.A. in English from Bennington College in 1977 and an M.A. in English from Columbia University in 1981.

In The Omnivore's Dilemma, Pollan describes four basic ways that human societies have obtained food: the current industrial system, the big organic operation, the local self-sufficient farm, and the hunter-gatherer. Pollan follows each of these processes—from a group of plants photosynthesizing calories through a series of intermediate stages, ultimately into a meal. Along the way, he suggests that there is a fundamental tension between the logic of nature and the logic of human industry, that the way we eat represents our most profound engagement with the natural world, and that industrial eating obscures crucially important ecological relationships and connections. On December 10, 2006 The New York Times named The Omnivore's Dilemma one of the five best nonfiction books of the year. On May 8, 2007, the James Beard Foundation named The Omnivore's Dilemma its 2007 winner for the best food writing. It was the book of focus for the University of Pennsylvania's Reading Project in 2007, and the book of choice for Washington State University's Common Reading Program in 2009-10. An excerpt of the book was published in Mother Jones.
