Dear Readers,



          From the Coordinator’s Desk!

         From the Coordinator’s Desk! Dear Readers, Greetings! Water is life. It is vital and supports immense diversity of life on Earth. It’s a source of food, health and energy. Fresh water makes civilization possible. But fresh water, in turn, is not possible without a healthy planet and human actions are putting a healthy planet at risk. Over two thirds of Earth's surface is covered by sea and less than a third is taken up by land. As Earth's population continues to grow there is an ever-increasing pressure on the planet's water resources. Our oceans, rivers, and other inland waters are over exploited by human activities. In the process we take more and give back less to the nature and reduce the quality and poor water quality means water pollution. Clean water is essential for life, but most people don't think much about this precious resource. In developing nations the search for safe drinking water can be a daily crisis. Millions of people die each year particularly children from largely preventable diseases caused due to lack of clean water and improper sanitation. In the planets history pollution is recent problem due to industrial revolution in the 19th century as before that people lived more in harmony with their immediate environment. The pollution of environment spread relatively with increase in human population and other industrial developments. When Earth's population was much smaller, no one believed pollution would ever pose a serious problem. It was once popularly believed that the oceans were far too big to pollute. Today, with around 7 billion people on the planet, it has become apparent that there are limits. Pollution is one of the signs that humans have exceeded those limits.
         In this context, present issue contains a scientific article on bacteriological analysis of potable water from North Chennai along with other interesting topics such as use of eco-friendly water borne semiconductor inks, effect of climate change on sun’s ability to disinfect lakes and coastal waters, converting a smartphone into a microscope and many more. Hope this issue will bring awareness on water conservation and provide insights technology developments.
