"Potrebbero essere i peggiori incendi mai registrati sino ad ora". In questo modo la NASA ha descritto i roghi nelle foreste e nelle terre agricole che da settimane stanno inquinando numerosi paesi del Sud-est asiatico.
Le spesse nuvole di fumo, osservate attraverso i satelliti, provenienti da
Sumatra e
Kalimantan attraverso i venti hanno raggiunto la Malaysia e Singapore (leggi le
indicazioni del Governo - in inglese), dove in alcuni casi è stato necessario chiudere le scuole. Lo smog ha pure creato disagi al traffico aereo.

Decine di migliaia di persone, riportano le agenzie, soffrono oramai di infezioni respiratorie. Una simile situazione si era registrata già fra il 1997 e il 1998. Quest’anno però si aggiunge l’influenza dell’effetto El Niño, che provoca un clima ancora più secco.

La tradizione di accendere fuochi per fertilizzare i campi è una pratica agricola primitiva illegale usata ancora spesso dagli agricoltori di quest’area geografica.
