The issue of ecology has become the main issue in the international world. Every country has regulated its citizen to be more aware of the environment and also adapt the environmentally friendly habit. There are so many programs that the governments have created in order to make people change their habit that is mostly destructive or at least has no concern on the environment preservation. The programs include the reduction of vehicle emissions, the manufacturing of home appliances that are environmentally friendly, and the program of planting trees, the program of cleaning the garbage from the lake, river and s on.

The local government of the New York City in the United States for example, has created a tem that has authority to execute some actions related to the violation of the new environmental regulation. The green police are the name of the team. The team can take your car if it is known that your car does not fit the requirement of the standard level of gas emission. Or if you are running a business like restaurant or so, the authority can make an inspection on the source of your raw materials. So, it is a very good effort to make people become more aware on environmental issue.
