The haze is a direct effect of forest fire in Kalimantan and other parts of Indonesia due to slash and burn method of farming. The Indonesian authorities appear to have no power to control farmers from practising such methods. The haze is further worsened by open burning practised by most Malaysians. Open-field burning of rice straw by the rice planters and open burning of dried leaves and garbage done by the public are a few examples that done by Malaysian. Many are ignorant of the health effects of open burning.
