Supermarkets pulling Asia Pulp and Paper products off their shelves caught the attention of some readers this week.

Ms Mary Chan Pheck Li and Mr Jolly Wee said that this was a strong signal sent to companies who may be complicit in the burning in Indonesia that is causing the haze.

However, Mr Chan Yeow Chuan and Mr Francis Cheng highlighted the potential fallout from this move. Mr Chan said some of the products pulled were among the cheapest in the market; Mr Cheng cautioned that the reduction in supply may push prices of other brands up and he urged the authorities to watch out for profiteering. Mr Chan also expressed concern that the low-income may pay the price of any boycott and urged the supermarkets to donate the withdrawn products to the needy, instead of discarding them.
