of extinction.

Forest and plantation fires Indonesian palm oil plantations' poor practice and poor environmental responsibility, has led to massive haze problem annually. Since 1997 Indonesia has been struggling to contain forest fires, especially on the islands of Sumatra and Kalimantan. Haze occurs annually during the dry season and is largely caused by illegal agricultural fires due to slash-and-burn practices in Indonesia, especially in the provinces of South Sumatra and Riau on Indonesia's Sumatra island, and Kalimantan on Indonesian Borneo. The haze that occurred in 1997 was one of the most severe; dense hazes occurred again in 2005, 2006, 2009, 2013, and the worst was in 2015, killing dozens of Indonesians as a result of respiratory illnesses and road accidents due to poor visibility.
