The discipline i want to is epidemiology in my upcoming days. I just love the area that focuses on the diseases  sources,spread and study with them.

Environment as a discipline of Public Health:
environment as a disipline i mean that is  focusing on the impact of some scientifical factor like physics,chemistry  ,biology on the environment and human health. this factors are very related to each other which create a bonding , and if that fails ,or one of these increase or decreses may impact the environment and human also.
