Nearly 500 forest fires were recorded in Sumatra Island last August which caused a thick haze to descend on Riau in Indonesia and even in some parts of Malaysia. The burning of forests is blamed on the operations of oil palm plantations, wood suppliers’ concessions, and pulpwood plantations. Several schools were closed in Riau during the return of the deadly haze last week.
The haze pollution is a recurring problem in the region caused mainly by forest fires in Indonesia. Last June, the haze covered Singapore and many areas in Malaysia.

On Twitter, Indonesians expressed their concern about the return of the haze in Sumatra.
If Indonesia Prez dtg, pls tell Msian palm oil owners in Sumatra to burn more fires so tht SBY can see with his own eyes what Haze is.
