GENEVA, MARCH 15:

One in four deaths worldwide is due to environmental factors such as air, water and soil pollution, as well as unsafe roads and workplace stress, the World Health Organisation said on Tuesday.

An estimated 12.6 million people died in 2012 as a result of living and working in unhealthy environments, 23 per cent of all deaths reported globally, according to the new study.

“If countries do not take actions to make environments where people live and work healthy, millions will continue to become ill and die too young,” warned WHO chief Margaret Chan in a statement.

The report defines environmental causes broadly, drawing links between a long line of environmental risk factors such as pollution, chemical exposure, climate change, ultraviolet radiation and access to firearms and more than 100 diseases and injuries.

Environmental factors

As many as 8.2 million of the deaths could be blamed on air pollution, including exposure to second-hand smoke, responsible for heart disease, cancers and chronic respiratory disease, the report said.

Among the deaths attributed to environmental factors were 1.7 million caused by “unintentional injuries,” including road accidents.

The report also counted 8,46,000diarrhoeal disease deaths among environmental mortalities, adding that many were linked to pollution and unsafe drinking water.

The WHO reported 2,46,000 deaths due to intentional injuries, including suicides, which it linked to, among other things, the unsafe storage and access to firearms, but also to pesticides, which are used in a full third of the world’s suicides.

The report found that most environmentally-linked deaths happened in South-East Asia, which accounted for 3.8 million such deaths in 2012, followed by the Western Pacific region with 3.5 million.

The least affected region was the Americas, with 8,47,000 deaths blamed on environmental conditions.

Europe had 1.4 million environmentally-linked deaths, while Africa reported 2.2 million.

The WHO said better environmental management could prevent the deaths of 1.7 million children under five, who are especially prone to serious illnesses arising from respiratory infections and diarrhoea.

“There’s an urgent need for investment in strategies to reduce environmental risks in our cities, homes and workplaces,” said Maria Neira, WHO’s public health chief.
