Agriculture is the production of food and goods through farming. Agriculture was the key development that led to the rise of human civilization, with the husbandry of domesticated animals and plants (i.e. crops) creating food surpluses that enabled the development of more densely populated and stratified societies. The study of agriculture is known as agricultural science. Central to human society, agriculture is also observed in certain species of ant and termite.[1][2]
Agriculture encompasses a wide variety of specialties and techniques, including ways to expand the lands suitable for plant raising, by digging water-channels and other forms of irrigation. Cultivation of crops on arable land and the pastoral herding of livestock on rangeland remain at the foundation of agriculture. In the past century there has been increasing concern to identify and quantify various forms of agriculture. In the developed world the range usually extends between sustainable agriculture (e.g. permaculture or organic agriculture) and intensive farming (e.g. industrial agriculture).
Modern agronomy, plant breeding, pesticides and fertilizers, and technological improvements have sharply increased yields from cultivation, and at the same time have caused widespread ecological damage and negative human health effects.[3] Selective breeding and modern practices in animal husbandry such as intensive pig farming (and similar practices applied to the chicken) have similarly increased the output of meat, but have raised concerns about animal cruelty and the health effects of the antibiotics, growth hormones, and other chemicals commonly used in industrial meat production.[4]
The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials. In the 2000s, plants have been used to grow biofuels, biopharmaceuticals, bioplastics,[5] and pharmaceuticals.[6] Specific foods include cereals, vegetables, fruits, and meat. Fibers include cotton, wool, hemp, silk and flax. Raw materials include lumber and bamboo. Other useful materials are produced by plants, such as resins. Biofuels include methane from biomass, ethanol, and biodiesel. Cut flowers, nursery plants, tropical fish and birds for the pet trade are some of the ornamental products.
In 2007, about one third of the world's workers were employed in agriculture. The services sector has overtaken agriculture as the economic sector employing the most people worldwide.[7] Despite the size of its workforce, agricultural production accounts for less than five percent of the gross world product (an aggregate of all gross domestic products).

A farm is an area of land, including various structures, devoted primarily to the practice of producing and managing food (produce, grains, or livestock), fibres and, increasingly, fuel. It is the basic production facility in food production.[1] Farms may be owned and operated by a single individual, family, community, corporation or a company. A farm can be a holding of any size from a fraction of a hectare to several thousand hectares.

The Topic: 

Easier - Farming was once the chief way of life in nearly every country. People cannot live without food, and nearly all their food comes from crops and animals raised on farms. Many other materials such as cotton and wool also come from plants and animals raised on farms. Not many people farm for a living any more, but farming remains the most important occupation in the world.
Harder - Prior to the twentieth century, the typical American family lived on a small farm. They raised hogs, cattle, sheep, chickens, and planted corn, fruits, garden vegetables, hay, and wheat. Everyone worked long and hard, but the results were often meager. Families barely harvested enough food for themselves. This situation began to change during the last half of the 1800's and it changed remarkably in the next century.
Scientific methods and labor-saving machinery have made farming increasingly productive. The development of improved plant varieties and fertilizers has helped double and even triple the yields of some major crops. Scientific livestock care and breeding have helped increase the amount of meat and products that animals produce. At the same time, the use of tractors and other modern farm equipment has sharply reduced the need for farm labor.
