Something caught my attention for no apparent reason. I noticed people carrying their own shopping bags round the city, instead of the usual plastic bags. Being a skeptic, I did not think that the environment awareness had suddenly landed from Mars on this city and her residents in a span of 5 months, nor the Expo 2010 had in anyway contributed positively towards the a greener environment. It was all, unshamedly, down to the effect of charging for the use of plastic bags. And its effect is phenomenal. Money speaks louder than words.
