The island of Borneo is experiencing heavy deforestation . The Indonesian government has therefore set up a reforestation program in an area where the primary forest was cut down and the soil was burnt. Professor Willie Smits and the Borneo Orang-utang Survival Foundation (BOS) therefore replanted more than 1 300 varieties of tree on 2 000 hectares by using natural excrement-based and food waste-based fertilizers. Whilst the forest in this area normally has difficulties growing back when it has been cut, the results are spectacular : many kinds of trees have reappeared.
