World Water Day is being celebrated today to focus on the importance of well planned, sustainable management of fresh water resources. Everyone knows that every drop of water counts, but everyone takes it for granted and knowingly or unknowingly wastes water in our day-to-day activities. It is observed that in Indian cities, water scarcity is caused by poor management practices. Lot of water is lost in the water distribution network due to poor quality pipings, theft of water encouraged by corrupt municipal officials, etc.
On an average, about 40 liters of water is required by a person for drinking and sanitation and more than a billion people still lack access to fresh water supply around the world.
We must ensure that the water bodies are not polluted by untreated waste water discharges by the industries. Rainwater harvesting, recycling and use of sewage water for gardening and other non-drinking purposes, desalination of sea water and most importantly the prevention of flow of surface water into the sea are some of the “should be done” to conserve and augment the water supply to meet the impending water crisis world-wide.
Connecting the rivers - northern Indian rivers like Ganges with the water-starved southern rivers would have solved the water scarcity in southern part of India during summer months. In addition, this would have given a boost to the agriculture in some of the states to considerable extent.

Ground water pollution and water purifiers
It is reported that 33% of ground water of India is not fit to drink due to pollution. The pollutants are iron, fluoride, salinity and arsenic and the concentrations exceed the tolerance levels prescribed by the authorities. The ground water is one of the major sources of drinking water and the Indian government promised to provide safe drinking water to all by 2012.
Now, how the domestic water purifiers sold in the market at high costs is going to purify the water with pollution at such high levels. The high-pitch advertisements by the companies should clarify the limitations of such systems. In fact, the companies should replace the old models with the latest models at a considerable discount.
Thus, the consumers get a latest model meeting WHO drinking water standards. The consumers have a right to know whether using the old models they are compromising on the quality of water. If not, there is no issue.

Crazy to think human activity impacts climate
This title is reproduced from the excerpts from the interview of leading US atmospheric physicist S. Fred Singer by the Indian leading DNA Money. This supports fully the observations made by "icareforyou" consistently in his blogg: http://icareforyou2007.blogspot.com.
For the benefit of my fellow-forum members I reproduce some of the statements made by Prof. Singer.
1. The contribution from humans for the climate change in 20th century is only minute compared to natural causes.
2. Blaming only the CO2 for global warming is not justified when there are other much stronger greenhouse gases such as water vapour and methane are present in the environment. Data does not support IPCC views.
3. The Sun (solar activity), changes in the earth’s orbit and continental drift are responsible for the climate changes we are witnessing today. About 18 cm rise in sea level per century is the norm over 3,000 years.
4. Any drastic control on industrialization will make energy very expensive and affordable only by the rich.
"icareforyou" again emphasizes that industrial developments in developing countries should not be curtailed just on the sake of emission cuts. The climate change seen today is not reversible just by controlling the CO2 emission.
However, there is a need for developing cheaper and cleaner energy sources. Also, global efforts should be made to control emissions of other and much stronger GHGs such as: natural gases, methane, ethanol, N2O and CF4.
