The World Health Organization has reported that four million children worldwide die under the age of 5 from environmental hazards every year. The hazards include polluted water and exposure to chemicals. The report was compiled by two dozen science experts.
Most of the deaths result from malaria, diarrhoeal diseases, poisonings and acute respiratory infections. However, some thirty percent are related to environmental factors.
The region most affected is Africa. Other regions include parts of southeast Asia.
