This document discusses deforestation in Indonesia. It notes that Indonesia has only 1.3% of the world's land area but contains 10% of the world's plant species and mammal species. Deforestation is reducing Indonesia's forests and threatening endangered species. On average, 1.871 million hectares of Indonesian forests are lost every year, equal to over 50 soccer fields daily. The main causes of deforestation are uncontrolled logging, land conversion for palm oil and other plantations, and abuse of development policies. Deforestation negatively impacts the atmosphere, hydrology, soil and ecosystems. Wise forest management is needed to protect what remains of Indonesia's forests.
