The air quality in this city is horrendous . The pollution levels are so high that we are not supposed to go outside with a face mask again !   Exhaust fumes from vehicles cause a great deal of damage to the environment .   On top of that , there are a few large chemical factories in the suburbs , which are contributing to the high pollution levels in the water and the air in this city .   As much as I love this city , I think I'm going to find a greener city to live in . Living in a polluted city like this just can't be good for my health .
