Many countries have set controls on pollution emissions for transportation vehicles and industry. This is usually done to through a variety of coordinating agencies which monitor the air and the environment. At the United Nations , the Atmosphere Management Program carries out world wide environmental projects. In the United States, the primary federal agency is the Environmental Protection Agency . Many state and local organizations also participate in monitoring and controlling the environment.
Prevention is another key to controlling air pollution.
The regulatory agencies mentioned above play an essential role in reducing and preventing air pollution in the environment. In addition, it is possible to prevent many types of air pollution that are not regulated through personal, careful attention to our interactions with the environment. In the United States, most household products come with instructions about safe use. Building materials should be reviewed for potential harmful effects.
