Over the past few weeks, the coronavirus outbreak has led to some rushing to buy and use masks.

During my early morning walks around the neighbourhood, I have noticed, to my dismay, used masks discarded in various places, including void decks, playgrounds and the open field in a park. They have become a daily eyesore.

It is ironic that masks have become a source of contamination, thanks to the callousness of some.

And it pains me that these people do not spare a thought for the sweepers who have to clean up the mess.

It really doesn't take much to be considerate. I hope we will all do our part and dispose of our used masks responsibly.
