Finally, perhaps the most important

Finally, perhaps the most important solution to Phoenix’s air quality problem is the construction of a light-rail train system. This system was completed in 2008. It provides transportation within the city of Phoenix, and it connects Phoenix with the cities of Tempe and Mesa. People can easily reach downtown Phoenix to work or socialize. The number of people using the light rail system is increasing. Its original goal was to carry 26,000 passengers daily, but within the first year the number reached 35,000 riders each weekday. People are beginning to change their lifestyles in order to take the train instead of their cars. With fewer cars in the downtown areas, there will be less pollution and the air quality will improve.
     Phoenix still has a long way to go before the clean air returns completely. Hopefully, though, with all of the regulations and changes in lifestyle, the pollution will eventually decrease to a level that is healthy for its residents.
