There are many ways to reduce air pollution. The government and citizens have a collective responsibility in the prevention and control of air pollution. Although people do not have enough resources to repair the damage caused by it, the prevention will gradually show improvements. In other ways, we could set limits on certain air pollutants to control if the emissions are higher than the specified level. Or easier we take public transport or carpool to reduce vehicular emissions. Also, they encourage everyone to plant more trees which will absorb the harmful gases and make the air cleaner. Avoiding fire-crackles at festivals and celebrations can also reduce air pollution. Above all, we must adopt the habit of recycling. So the environment will be cleaner and the air pollution could be improved.
