This is the VOA Special English Agriculture Report. Seth DeBolt is a plant scientist at the University of Kentucky in the United States. He and other scientists wanted to find a source of fuel that poor people in rural areas of developing countries could use to make electricity. The United Nations Development Program says a billion and a half people have no electricity. A billion others have an undependable supply. Professor DeBolt went on a study trip to rural Indonesia. He saw that, everywhere he went, there was very little waste in the use of agricultural products. Everything that farmers grew was used for something. Even the remains of fruit that people did not eat were fed to chickens.
