Environmental health issues

How healthy is your world?

WHO/Chris de Bode

"Drinking water, basic sanitation and nutrition, because these are a major health hazard for the majority of children in the world," -- Prakash Shrestha, Nepal

"The effects of environmental issues, such as global warming on health," -- Krista Townsend, Canada

Another global health priority you identified was the link between our health and the environment we live in, from the water we drink, to the air we breathe, to the food we grow and eat. More than three million children under the age of five die each year from environment-related causes, such as polluted indoor and outdoor air, contaminated water and lack of adequate sanitation.

WHO's programmes and initiatives on water and sanitation, vector-borne diseases, indoor air pollution, chemical safety, transport, ultraviolet radiation, nutrition, occupational health, food safety and injury prevention all address issues critical to improving environmental health.
