Yes, Krishnan. I must agree that much depends on each person. We should first think about what each of us is doing to conserve water resources.

People are wasting water because it is easily and freely available. They are not understanding the value of wasting water, how they are affecting the future?

Educating and creating awareness about the value of water in future, may help.

Restricted supply of water and regulating the use of water may also help.

I feel that people living is areas where they don't face water shortages are at fault in the sense that they feel that the nature's bounties are for them to use or say misuse, with out any fear of loosing the privilege and I am often at loss to understand this callous attitude

I have seen people wasting water just because they don't care, and fear that with such attitude the time is not far when, even areas with sufficient ground and surface water would be feeling the pinch of water shortages soon.

Both urban and rural areas suffer from this malice. In urban areas poor water supply system with leaking pipes results in wastage of millions of liters of drinking water every day. No provisions of rain water harvesting to recharge ground water is resulting in water table going down each successive year.

During summers more and more areas now face water scarcity. We must understand that if the ground water sources are not recharged a time will come when there just would not be any water left to pump out. Similar is the case in rural areas, e.g. irrigating crop through flooding method, which is the most common practice results in huge loss of water season after season, year after year.

It is time to take note of these inefficient systems of water use and inculcate the habit of treating water as a scarce resource which must be used judiciously and economically. Educating the masses about its importance is thus need of the hour.

Thank you

I believe that in such an important issue must take into account many aspects. Frugality to the gifts of nature (water, forests, fields for harvest wild animals ...), and those creatures that are created and work of generations (architecture, painting, literature, theater ...). So, you ask about the water. It is important for every person to the rational use of water. This is achieved by a common culture and traditions of the people. Now this is not enough, because the moral qualities of the people have changed. Consequently, the need for a reasonable education in the family and school solicitous attitude to water. The next level of rational use of water - it's public institutions - government, firms, corporations ... the need for national and international laws, programs, rational use of water. And, most importantly, reasonable estimates the water situation in the future. Creation of technical business solutions for the delivery of water through pipelines or by tankers, balloons and other devices from places with abundant water resources in those areas and countries where "reigns water famine." In conclusion, I can say, it is necessary not only unsubstantiated talk about the problem of water and other issues are also very important. We should really take steps to address the problem.

@ Subhas C Kundu, Thanks for your first reply on such an important issue. Yes I am totally agree with you that educating and creating awareness in masses will help to secure our future on water front. Thanks and regards

Dear Prof. Paul R Yarnold, Thanks for your suggestions. It is really important to search some global solution, privatization is not a very good preposition for me too. Thanks and regards

My Dear Dr Singh, Thanks for your detailed reply. It is true that now it is time to inculcate the habit of water saving from childhood. Efficient use of water should be character of individual globally. Thanks

@ Prof.Vladimir A Kulchitsky, thanks for your elaborated comments I am also very much of the opinion that not only water other gifts of nature should also be rationally utilize. Very true that the efficient use of water and other natural resources must be taken on top priority to save our planet from many adversities and pass on the resources to our next generation in good shape. Thanks for your valuable comments. regards

The future wars will be over water.

A comprehensive online database of water-related conflicts—the Water Conflict Chronology—has been developed by the Pacific Institute.This database lists violence over water going back nearly 5,000 years.

Dear Sir @ Costas Drossos, very rightly mentioned next world war will be on water. But Sir, we can avoid it by changing our attitude towards the wastage of water. Thanks for your suggestions and such an important link. Regards

Dear Sarwan,

I agree with you,  we can avoid it by changing our attitude towards the wastage of water, but it seems that humanity cannot solve almost every simple such problem, because of very different reasons and especially power games!

Respected @ Prof Costas Drossos, Sir I could not able to understand why these very different reasons and power games plays with such a simple humanity problems. At least they may spare the the life causing resources. Let us pledge to make a society with the attitude for saving such a important natural resource like water. Thanks and regards

Use every drop. Learn to repurpose water. One easy way is to capture under your colander the potable water you use to rinse fruits and veggies, and deposit it in the garden. Double-dip dishes. Take a page from the past and make smart use of dual sinks. Instead of letting the water run while you wash dishes, fill one sink with hot, soapy water for washing, and the other with cool, clear water for rinsing.

Yes, Krishnan. I must agree that much depends on each person. We should first think about what each of us is doing to conserve water resources.

Thanksfor your valuable and thought provoking discussion @ Prof. Krishnan Umachandran and @Dr.Vladimir A.. We each and every person should have to become a poineor in the case of water saving. Thanks for the link provided by@Umachndran. Thanks and regards.

Hi Dear All, May I invite your attention towards the habits we have inculcate for water wasting with time. Your comments.

Dear Sarvan! It is a good idea. Let me again saying: Habit is a second nature. So it is necessary to pass from birth habits of thrift to the gifts of nature (and therefore to the people). Then society will be more people who respect the gifts of nature. And not only an exceptional gift - itself.
