Since the time men learnt to grow crops, agriculture has been the main source of food. Today, most of the people in all parts of the world, especially in developing countries, are engaged in agricultural activities.
Human is mainly a grain-eating animal. In Asia, most of the people eat rice. In Europe, North America and Australia, wheat is the main food crop. If rice and wheat cannot be grown, millet and other cereals are grown as food crops. Though men also eat meat, they enjoy eating meat only when they take it together with rice or bread which is made from wheat. It is therefore clear that grains are the main source of man’s food, and grains are agricultural products.
Men, however, cannot live on grains alone. They need other foods too to make his meals more palatable. Therefore, they learnt to grow vegetables, potatoes and fruits. Like grains, these things come from the soil. They have to be planted and grown with great care. As a result, men have made many experiments on soil for several centuries to increase their production of crops. Men have also learnt to consume dried leaves to refresh themselves. Tea and tobacco, the dried leaves of certain plants, have become very popular as sources of refreshment. Even coffee and cocoa are products of plants. Cotton, jute and other fiber are used to make cloth and several other things for our daily needs. All these plants have become very important in agriculture.
In some countries, agriculture is a main source of wealth. The rubber tree and the oil-palm in Malaysia bring millions of dollars every year. In Bangladesh, the jute plant is the main source of wealth. Similarly, in almost every country there is at least one plant which makes a great contribution to the economy of the country. We arrive at the conclusion that agriculture play an important role in men’s world.
Why is agriculture important in the world of today?
Since the dawn of history, agriculture has been one of the important means of producing food for human consumption. Today more and more lands are being developed for the production of a large variety crops. In Asia, vast areas of land are being used to produce rice, wheat, rubber and a variety of other crops. In Asia, vast areas of land are being used to produce rice, wheat, rubber and a variety of other crops. More than half of the lands occupied and developed by human beings in the world are devoted to agriculture.
That agriculture is one of the most essential means of producing food is realized easily when we think of the types of things that we eat. The rice or wheat that we eat comes from the land. Even potatoes and other roots or vegetables and even leaves such as tea, as well as the fruits that men eat are the products of the soil that covers the earth. In fact, everything that we eat except meat, fish and other kinds of flesh comes from the land and what grows on the land is part of agriculture. Even the sugar, oil, coffee and other beverages that we use are products of plants that grow on the land. In the same way, many of the medicines that we use are made of plants that grow in various parts of the world. The tobacco that we use for relaxation also comes from a plant.
Thus, it can be easily observed that without agriculture we would be almost without food. It is true, however, that in the remote past men did live mainly on flesh that he obtained by hunting. But such a kind of life was unhappy and inconvenient, for animals were not found everywhere easily. Therefore, men turned to agriculture for his livelihood. Today, agriculture continues to provide almost all the foods that men require to survive on the earth.
