From ancient times the Negritos led a nomadic lifestyle, using the rich natural resources of the country. Their traditional way of life of jungle hunter-gatherers is considered to be the most primitive among all indigenous groups. Now a large part of the Negritos live in permanent settlements, but periodically they go to the jungle to hunt or harvest wild berries. They collect some jungle produce, including rattan and aloe plant, for sale. This way of life is due to the fact that the Semangs are often considered nomads and the most economically backward group of the Orang Asli.
