Tog mentioned the Orang Asli. Here is an old film showing them going about their business in the jungles of Malaya. They have fantastic bushcraft skills, and make a lot of use of banana leaves for wrapping and cooking food, as shown in the video.
The government has been trying to get them to settle in permanent villages and convert them to Islam, and I fear many of them may be losing touch with their jungle skills and culture.
