Drivers ignoring idling engine ban a huge problem in HK

All drivers in Hong Kong, whether it is trucks, taxis, private cars, buses or minibuses, have one thing in common. They leave their engines on while stationary.
Sometimes they are not even in the vehicle. They eat their lunch and sleep with the engine idling, sometimes for hours. Pedestrians pass by, seemingly unaware that this is a huge problem.
It seems they do not care that the law banning idling engines is being routinely flouted and I find this very frustrating.
I am not sure if Hongkongers have been educated about the environment. Everything you do has an impact and leaving the engine on is bad for the environment and for people's health.
There is clearly a lack of education in local schools. Students in Hong Kong may excel in maths, but know little about environmental issues.
We have an obligation to educate the next generation about the impact we have on the place we call home.
Sadly, many adults don't care about being eco-friendly either. Their priority is to make money. Hongkongers are wasteful, and take precious resources for granted - electricity 24/7, running water and the assumption that someone will always pick up their trash.
