Agriculture is the cultivation and breeding of animals, plants and fungi for food, fiber, biofuel, medicinal plants and other products used to sustain and enhance human 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. The history of agriculture dates back thousands of years, and its development has been driven and defined by greatly different climates, cultures, and technologies. Industrial agriculture based on large-scale monoculture farming has become the dominant agricultural method.
Modern agronomy, plant breeding, agrochemicals such as pesticides and fertilizers, and technological developments have in many cases sharply increased yields from cultivation, but at the same time have caused widespread ecological damage and negative human health effects. Selective breeding and modern practices in animal husbandry have similarly increased the output of meat, but have raised concerns about animal welfare, environmental damage (such as massive drainage of resources such as water and feed fed to the animals, global warming, rainforest destruction, leftover waste products that are littered), and the health effects of the antibiotics, growth hormones, artificial additives and other chemicals commonly used in industrial meat production. Genetically modified organisms are an increasing component of agriculture, although they are banned in several countries. Agricultural food production and water management are increasingly becoming global issues that are fostering debate on a number of fronts. Significant degradation of land and water resources, including the depletion of aquifers, has been observed in recent decades, and the effects of global warming on agriculture and of agriculture on global warming are still not fully understood. However, entomophagy would solve most of the former problems, and may start to gain popularity among society in the West.
The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials. Specific foods include cereals (grains), vegetables, fruits, oils, meats and spices. Fibers include cotton, wool, hemp, silk and flax. Raw materials include lumber and bamboo. Other useful materials are also produced by plants, such as resins, dyes, drugs, perfumes, biofuels and ornamental products such as cut flowers and nursery plants. Over one third of the world's workers are employed in agriculture, second only to the service sector, although the percentages of agricultural workers in developed countries has decreased significantly over the past several centuries....LESS
ADDIS ABABA, Ethiopia (AP) — Ethiopia's leader has rejected arbitration by the World Bank on a disagreement with Egypt over the hydroelectric dam that Ethiopia is building on the Nile River. Prime Minister Hailemariam Desalegn on Saturday refused the suggestion made by Egypt in late December that the World Bank should be brought in to resolve the dispute with Ethiopia over the construction of the dam on the Nile River that Egypt says threatens its water security. Sudan is also part of the negotiations because the Nile flows through it on the way to Egypt.
MORGANTOWN, Miss. (AP) — A 99-year-old hunter in Mississippi wants to know why people are making a big fuss about her recent kill. It was a doe after all, not a prized buck. The Clarion Ledger reports that Bertha Vickers used a .243 Winchester rifle to kill a doe recently a few miles from her rural home. Relatives posted pictures of Vickers and her kill on Facebook, and people sent messages of congratulations.
