Agriculture is the main source of national income for most developing countries. However, for developed countries, agriculture contributes a smaller percentage to their national income. The agricultural sector provides fodder for domestic animals. The cow provides people with milk which is a form of protective food. The development of agriculture led to the rise of civilizations. People had to stay in one place in order to grow and harvest crops. They also needed buildings in order to store crops. Many civilizations in the Middle East invested in irrigation structures in order to provide for stable water.
