Can you describe five effects of air pollution on human health?
I think if you just stick with respiration you will have more than enough to contend with.
The reason for my saying this is simple. Every organ in our body relies upon oxygen brought into our bodies through our lungs. From the lungs it enters our blood and then of course it is circulated to every organ and every portion of our bodies. Hence, the greater the pollution you inhale, the greater the damage done to all organs.
