The second major advance came as a result of Spanish explorer Christopher Columbus’s voyages to the New World in the late fifteenth century. The connecting of the New World and the Old World saw the exchange of farming products and methods. From the New World came maize (Indian corn), beans, the “Irish” potato, squash, peanuts, tomatoes, and tobacco. From the Old World came wheat, rice, coffee, cattle, horses, sheep, and goats. Several Native American tribes adopted new lifestyles, notably the Navajo as sheepherders and the Cheyenne as nomads (wanderers) who used the horse to hunt buffalo. In the twentieth century, maize is a staple food in Africa.

The Industrial Revolution of the eighteenth and nineteenth centuries both contributed to and was supported by agriculture. The greatest agricultural advances came in transportation, where canals, railroads, and then steamships made possible the shipment of food. This in turn increased productivity, but most important, it reduced the threat of starvation. Without these massive increases in food shipments, the exploding populations could not have been fed and the greatly increased demand for labor by emerging industries could not have been met.

As a consequence, the Industrial Revolution introduced major advances in farm technology, such as the cotton gin, mechanical reaper, threshing machine, mowing machine, improved plows, and, in the twentieth century, tractors and trucks. These advances enabled fewer and fewer farmers to feed larger and larger populations, freeing workers to fill demands for factory labor and the growing service industries.

Finally, scientific advances of the twentieth century—the refrigeration of meat, the development of hybrid crops, research into genetics— have greatly benefitted agriculture. Great potential exists for the development of crop and animal varieties with greatly improved dietary characteristics, such as higher protein or reduced fat.

Drawbacks to the rise of agriculture

The agricultural revolution is also associated with some of humankind’s darker moments. In the tropical and subtropical climates of the New World, slave labor was used extensively in farm fields in the eighteenth and nineteenth centuries. In the late twentieth century, the mass production of animals, especially in close quarters, has been extremely controversial. While farmers view new breeding practices as useful means to producing more food, animal rights activists protest them as showing a disregard for animals’ comfort and welfare. Additionally, the widespread use of fertilizers, pesticides, and other chemicals in agriculture have led to serious pollution crises in many areas of the world.

Famine throughout history shows mankind’s desperate dependence on agriculture. Advances in farming, especially in the last few centuries, have led to increases in population. Growing populations—made possible by food surpluses—have forced agricultural expansion onto less and less desirable lands. Because agriculture drastically simplifies ecosystems (communities of plants and animals) and greatly increases soil erosion, many areas such as the Mediterranean basin and tropical forestlands have severely deteriorated.

The future of agriculture

Some argue that the agricultural revolution masks the growing hazards of an overpopulated, increasingly contaminated planet. In the nineteenth and twentieth centuries, agriculture more than compensated for the population explosion. Through scientific advances in areas such as genetic engineering, there is hope that the trend will continue. However, the environmental effects of the agricultural progress could soon undermine any advances if they are not taken seriously.
