Singapore, environmentallly friendly?

Over the years, the Singapore government has encourage the citizens to play a more active roll in rescuing the environment. However, has all these plans worked, has Singapore citizens become a greener country? Perhaps, the project has not been entirely successful. For example, Singapore citizens have became more active in recycling. Even schools have been rolling out projects to encourage students to recycle. But, many people has forgotten about the "bring your own bag day" event. Now, many people hardly bring their own plastic bags to the supermarkets on Wednesdays. Even the cashiers did not remember about the project. They have started giving out plastic bags on Wednesdays even when the custiomers are supposed to bring their own bags.
In the recessions, being environmentally friendly could be a help in reducing expenses. For example, by buying bulbs which use less energy, not only can we save money on electicity bills, we can also reduce the anout of electicity used, and saving the environment. However, buying a hybrid car which uses less petrol might not be cost-effective even if it is environmentally friendly. The car would definitely cost much more and even the fuel is more expensive.
