Nearly a quarter of global diseases are caused by exposure to avoidable environmental hazards, the World Health Organization (WHO) said in a report on Friday. Environmental exposures cause as much as 24 percent of all diseases, and more than 33 percent in children under the age of five, said the report, titled ‘Preventing disease through healthy environments — towards an estimate of the environmental burden of disease.’ Well-targeted interventions could prevent much of this environmental risk, saving as many as four million lives a year, mostly in developing countries, the report added. WHO said the new report was the most comprehensive and systematic study yet undertaken on how preventable environmental hazards contribute to a wide range of diseases and injuries. By focusing on the environmental causes of diseases, and how various ones are influenced by environmental factors, the analysis breaks new ground in understanding the interactions between environment and health, the Geneva-based organization said.
