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.
