Millions of deaths due to ‘unhealthy environments’

An estimated 12.6 million people died as a result of living or working in an unhealthy environment in 2012 – nearly 1 in 4 of total global deaths, according to new estimates from 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. 

The second edition of the report, “Preventing disease through healthy environments: a global assessment of the burden of disease from environmental risks”, reveals that since the report was first published a decade ago, deaths due to non-communicable diseases (NCDs), mostly attributable to air pollution (including exposure to second-hand tobacco smoke), amount to as much as 8.2 million of these deaths. NCDs, such as stroke, heart disease, cancers and chronic respiratory disease, now amount to nearly two-thirds of the total deaths caused by unhealthy environments. 

At the same time, deaths from infectious diseases, such as diarrhoea and malaria, often related to poor water, sanitation and waste management, have declined. Increases in access to safe water and sanitation have been key contributors to this decline, alongside better access to immunisation, insecticide-treated mosquito nets and essential medicines.

“A healthy environment underpins a healthy population,” said Dr Margaret Chan, WHO director-general. “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.”

The report emphasises cost-effective measures that countries can take to reverse the upward trend of environment-related disease and deaths. These include reducing the use of solid fuels for cooking and increasing access to low-carbon energy technologies. 

“There’s an urgent need for investment in strategies to reduce environmental risks in our cities, homes and workplaces”, said Dr Maria Neira, WHO director, Department of Public Health, Environmental and Social Determinants of Health. “Such investments can significantly reduce the rising worldwide burden of cardiovascular and respiratory diseases, injuries, and cancers, and lead to immediate savings in healthcare costs.” 

Environmental risks take their greatest toll on young children and older people, the report finds, with children under five and adults aged 50 to 75 years most impacted. Yearly, the deaths of 1.7 million children under five and 4.9 million adults aged 50 to 75 could be prevented through better environmental management. Lower respiratory infections and diarrhoeal diseases mostly impact children under five, while older people are most impacted by NCDs. Looking across more than 100 disease and injury categories, the report finds that the vast majority of environmentrelated deaths are due to cardiovascular diseases, such as stroke and ischaemic heart disease.
