I applaud supermarket chains FairPrice, Sheng Siong and Prime Supermarket for pulling Asia Pulp and Paper products off their shelves ("Supermarkets pull plug on haze-linked firm's products"; yesterday).

For the past few years, the haze has affected our lives, increasing our costs in having to buy masks and air-purifiers, and in greater use of the air-conditioner.

People cannot enjoy outdoor activities and outdoor businesses see a drop in business when the haze hits.

Some events have seen last-minute cancellations, causing inconvenience and incurring costs.

Schools even closed for a day this year ("Haze forces closure of schools across S'pore"; Sept 25).

Medical costs also rise, with more people seeking treatment for respiratory and skin problems.

It is good that the supermarket chains have taken a strong stance against a company linked to forest fires in Indonesia causing the haze.

We can join in the fight against the haze by boycotting companies linked to the burning.
