As I am trying to say, polluted air can affect our health in many ways. Examples include irritation to the eyes, nose and throat, and upper respiratory infections such as bronchitis, chronic respiratory disease, lung cancer, heart diseases and even damage to the brain, nerves, liver, and kidneys. Air pollution can also worsen the medical conditions of individuals with asthma. In the great "Smog Disaster" in London in 1952, four thousand...
