Reducing environmental risks could prevent 1 in 4 child deaths. In 2012, 1.7 million\u00a0deaths in children under five were attributable to the environment. These included 570 000 deaths from respiratory infections, 361 000 deaths from diarrhoea, 270 000 deaths from neonatal conditions, 200 000 deaths from malaria and 200 000 deaths from unintentional injuries.<\/p>\n
Environmental risks have an impact on the health and development of children, from conception through childhood and adolescence and also into adulthood. The environment determines a child\u2019s future: early life exposures impact on adult health as fetal programming and early growth may be altered by environmental risk factors.<\/p>\n
Adverse environmental conditions and pollution are a major contributor to childhood deaths, illnesses and disability, particularly in developing countries.\u00a0<\/p>\n
Children are particularly vulnerable to certain environmental risks, including: air pollution; inadequate water, sanitation and hygiene; hazardous chemicals and waste, radiation; climate change; as well as emerging threats like e-waste.<\/p>\n
