The United Nations, today, celebrates World Water Day with a focus upon issues of sanitation. In accordance with that focus, the Water Day site supplies links to photos, videos and factsheets regarding sanitation essentials and efforts by UN organizations to supply support and remediation.
Additionally, the UN Water site supplies links to reports and news about water scarcity, water quality, statistics and water policies. According to this site, “it is estimated that 88% of the global burden of disease is attributable to unsafe water supply, lack of sanitation and hygiene and is mostly concentrated on children in developing countries. Every day, this contributes to the deaths of 5,000 children from largely preventable causes, including diarrhoeal diseases and parasites.”
