Barter with water

Prior to the use of currency for doing various transactions, ancient people were engaged in less complicated system called bartering, where they used to exchange different utility oriented products with each other. With the passage of time people became more refined and choose currency as their preferred mode of transaction. But with the increase in depletion of ground water, in near future the age old barter system is about to revive.

At this moment water is considered as the most precious natural resource in the world leaving behind oil (petroleum) in the race. The world has witnessed different conflicts, political tensions eventually leading towards war over the control of oil. But soon the world is going to witness the mother of all war, which will be over the domination of water. Even one litre of water will fetch thousands of dollars at that time. The socio-economic model of the world will be reshaped considering the amount and value of water in a region.

Presently there is only 3% of fresh water in planet earth out of which 2% is trapped in glaciers and polar ice caps and only the existing 1% is left for the use of humans and animals. In near future abundant water for drinking, sanitation, industry, irrigation, transportation and recreation will become a dream and nightmare at the same time. Looking at the rate of increase in population it is even hard to imagine how critical the scarcity of water will become in the years to come.

It has been predicted that by 2025 around 2 billion people leaving in different countries will be part of a hydrological war to meet the needs of agriculture, industry and households. Lester Brown, president and founder of the Earth Policy Institute, a Washington based independent research organisation while discussing about this issue once said, “There are substitutes for oil but there are no substitutes for water. Excessive pumping for irrigation to satisfy food needs today almost guarantees a decline in food production tomorrow.”

In future to ease the tension arising out of scarcity of water the world leaders have to look back towards barter system. Adding monetary value to water will bring doomsday for the world. As only the powerful and rich nation in the world will then be able to posses the right to water and the rest will have to fight among themselves for the minimum amount of water needed for survival. Following the barter system the looming crisis can be solved to some extent. Nations with rich water resource can barter water with the other nations that have abundant supply of some other product.

By this system the water starved nation will receive their desired amount of water and the water rich nation will be enriched with the resource they were lagging earlier.

Going black, Blackle saves energy

Blackle.com is generating lots of news these days, when saving energy for a better future and environment is the buzzword. Blackle.com, developed by Heap Media Australia is a website powered by Google Custom Search. It has come up with an unique idea to save energy, by transforming itself into black.

The idea behind this concept is to reduce climate change by saving energy. The creators of Blackle believe that ample amount of energy can be saved by the use of monitors by providing search with a black background. The scientific theory backing Blackle is that the display of different colours consumes different amounts of energy on computer monitors. A study conducted in 2002 by Roberson on a variety of CRT and LCD monitors found that an all black screen consumes less energy than an all white screen.

Heap Media’s fundamental intention in launching Blackle was to spread the awareness of “save energy” among the 500 million (approx.) computer users all over the world. In January 2007, a blog post titled ‘Black Google Would Save 750 Megawatt-hours a Year’, triggered the idea, which finally took its shape into Balckle.com.

As an environmental friendly initiative, Blackle encourages every user to set Blackle as their home page. By doing this every time a user loads Internet browser they will start saving a little bit of energy. Search Engine major, Google supported this project because their expand and reach will not only spread the idea of energy conservation but more importantly save energy to a great extent.
