Question

write a composition of 250-300 words based on agriculture

Answer 1

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.[1] 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 methodology.

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 and the health effects of the antibiotics, growth hormones, 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.

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.

Answer 2

The word agriculture is derived from the Latin word 'ager' and 'cultura' which refers to field and cultivation respectively. In the history of agriculture, it began independently through the collection of grains to fulfill the hunger. Different countries were involved in the process of agriculture differently. For instance, in New Guinea, certain root vegetables and sugarcane were cultivated around 9000 years ago. Rice was cultivated in China around 13,500 years ago, in Peru, cotton was domesticated, and so forth.

Nowadays, with the advancement in technology, modern techniques are being used in agriculture. Through such advancement, it has lead to great development in the sector of agriculture. While with the pros of technology, there are negative aspects as well. The use of pesticides and fertilizers though yields the crop drastically, however, it harms ecology. It tends to harm the health of humans as well. Lastly, the use of modern practices and selective breeding has led to the meat supply increasingly. Such supply has raised the concern about animal welfare majorly.

At last, the agriculture sector has evolved over the period of time and brought many positive as well as negative cause to the society.
