According to a report by the World Health Organisation and Unicef, toilets are undervalued in the industrialized west; however, it's still a luxury for one-third of people in the world who don't have this facility.

As per a report, those who don't have toilets carry on polluting water sources and putting public health and safety for millions at risk throughout the world. It is also leading to childhood stunting and malnutrition and every year and weakens 161 million children both physically and mentally.

According to the WHO's public health department director, Dr. Maria Neira, "Until everyone has access to adequate sanitation facilities the quality of water supplies will be undermined and too many people will continue to die from waterborne and water-related diseases".

Every year, diarrheal diseases lead to death of 700,000 children and better sanitation could have prevented most of the losses of lives.

Development on global targets set in 2000 is evaluated by the joint report released by the UN agencies. These targets include giving every person access to clean drinking water in addition to sanitation facilities. Other goals in areas like poverty, disease, hunger and inequality have also been included in the list.

According to the report, there has been some success in previous efforts for improving water and sanitation and since 1990, 2.1 billion people gained access to better sanitation facilities. However, another 2.4 billion have not seen any signs of improvement.

As per report, India is having the worst condition with over 640 million people relieving themselves in the open.
