You said "The government has failed to educate society"

What society? the majority of the society are not local citizens, and the majority of the non-citizens are labor workers who contribute very little to the problem.

Most of those who come here and afford buying a "big" car will do so, why? was it they were not educated well about environment in their countries?

Socio-economics here plays a different game that in Europe or US. Many who cannot afford driving "any" car in Europe, will drive a V6 car here, becuase they afford it and they would do the same in Europe, regardless of the efforts of the government to protect the environment.

Prove me wrong Nic, what you did to protect the environment here?
