Environmental health is concerned with how both the natural and built environment affect human health by looking at the impact of physical, chemical and biological factors external to humans. Those working in Environmental health fields are concerned with preventing diseases or other illnesses by assessing and controlling environmental factors that pose a threat to human health whether it involves air quality, natural disasters, radiation, water quality, UV exposure, indoor air pollutants, climate change, healthy communities and work environments, or the effects of toxic substances. Environmental health can also refer to ecosystem status or function. Chemicals, diseases, and invasive species threaten to alter wildlife and plant populations, which in turn may impact ecosystem function. Maintaining health, whether ecosystem or human arguably presents one of the greatest challenges of the day, in general maintaining optimal ecosystem function is essential for continued survival of all species including humans.
