A Unicef-World Wide Fund for Nature (WWF) combined study has warned of a serious water crisis in India. The consequences would be more health problems for the people and more shortage of quality warer for agriculture and industries. The study has found that no less than 44 million people in India suffer from water related problems caused, according to it, either by pollution, or prevalence of fluoride or arsenic or iron deposits, or due to ingress of salt water. The study believes the situation is not the result of natural factors, but has been caused by humans.
