water purification systems

Every human being has the right to safe and pure drinking water but we still see many people in rural areas without the facility of clean drinking water. It is alarming to see that millions around the world still consume the unclean water.

Also water pollution is a main hazard to be conquered in this arena. Due to consumption of impure drinking water lakhs of people die every year globally. Urban people have high technology water purifiers while rural people still require the help. With the issues of global warming lurking around, the situation might get worse. Our body is made up of 70% water which makes the requirement of safe drinking water a mandatory thing. Governments are least bothered to provide the free safe drinking to the lesser privileged people on humantarian grounds. These days even nongovernmental organizations have their vested interests rather than doing pure service to mankind. It is very important to devise cheap water purifiers to cater the basic need of millions of people around the globe who do not have access to safe drinking water. The plight of poor people has been long unheard while the governments keep changing and urban people continue to live a luxuriously life. The governments should open avenues for free installation of water purifiers for public use among poor people.
