The environment is a major determinant in health and wellbeing.

According to WHO, environmental risk factors, such as air, water and soil pollution, chemical exposures, climate change and ultraviolet radiation, contribute to more than 100 diseases and injuries; an estimated 12.6 million deaths each year are attributable to unhealthy environments - nearly one in four of total global deaths.

Meanwhile, human activity and economic development exert great impact on and now threaten the planet on which we depend for health, wellbeing, and survival. Earth system processes on the planet have boundaries or thresholds which should not be crossed; and planetary life support systems are essential for human survival, such as climate change, biodiversity loss, and ozone depletion, among others.

Since the Stockholm Declaration in 1972, Member States and the UN system have been working to ensure a healthy environment for all. Managing these boundaries and factors is critical for achieving health sustainable development.

For example, one of the most common and fastest growing environmental influences is EMF (electromagnetic fields). As technology advances, people are now exposed to varying degrees of harmful EMF and the levels will continue to increase, which causes more and more concerns and anxiety. At the same time, new technologies such as PEMFs and terahertz irradiation are being developed to alleviate or remedy the situation and bring healthy outcomes.
