Direct production :
All people have three basic needs -food, clothing and shelter -and many of the activities we engage in are aimed at satisfying those needs. Activity that results in the satisfaction of our needs is often referred to as 'economic activity', therefore, people ar sometimes called 'economic animals'.
Early people had a simple way of life. They would meet all of their needs themselves without the aid of others, and without the facility of money. This is called direct production. They would hunt animals and gather plants and berries. They were living in a subsistence economy - providing just enough to survive, but not to improve their way of life. We say that, at this time, man was a hunter-gatherer.
