it's an important factor to improve air quality becouse air quality is related to our health directly.

so , i'd like to suggest two solution to make.

first is reducing air pollutants generated by gasoline - powerde cars.

for example, owners of cars are forced to install somke-reducing filter on duty

or goverment promte to use eco-friendly fuels such as bio-diesel, compressed natural gas and hydrogen energy.

second is ventilating the air to use trees and water.

for instance, planting thousands of trees around roads and roofs of buildings to spray water on roads when traffic congestions is heavy

i'm sure that my solution will be helpful to improve air quality in my country.

if all of us will effort respectively, the air qualilty will be more improved and similar to those of advanced contries
