Why is all the fresh water not available for humans?

They claim that it can help retain original taste of coconut water for as long as up to 18 weeks. Fresh tender coconut water is a popular, low-calorie nutritious drink, but untreated coconut water has a shelf life of only 24 hours.

The new method involves eliminating suspended debris using a nylon mesh and sterilization through a hollow Polyacrylonitrile fiber tube for an hour. This process removes bacteria and other microbes which increases its shelf life, researchers said.

Coconit water thus sterilized was stored in wax-sealed glass or polypropylene bottles in a refrigerator at 5 degree Celsius and tested every month for quality and its properties.

Sterilization using membranes is known but it has been used for coconut water for the first time, and the polyacrylonitrile membrane used has been modified for this purpose, researchers said. He says that the new method of preserving coconut water maintained the clarity and taste for 18 weeks.

The results of the study have been published in Journal of Food Engineering. Amit Jain, professor at Department of Chemical Engineering, Guru Ghasidas Vishwavidyalaya, Bilaspur, who was not involved with the study but was one of the tasters, commented that the new method is better because it increases the shelf life without adding preservatives.

If membranes are maintained appropriately by routine cleaning, the method can be used on industrial scale and can also be optimized for other beverages, he said. Researchers claim the method can be scaled to an industrial scale in lesser cost. Currently available preservation methods such as pasteurization, microwave heating, freezing, and refrigeration have some limitations.

While heating reduces taste and quality, refrigeration increases cost during transportation that limits marketability.Jun 11,  · While the human body can endure a month without food, it can only go a week without water. Likewise, all plants and animals need water to survive.

Animals and plants, including humans, obtain most of their water from rivers, lakes and groundwater–the main sources of freshwater on earth. Without water the body will perish; that has already been established.

Another disadvantage of the body being deprived of water is the lack of oxygen and nutrients that water carries throughout the body. It seems there are few places in the solar systems without some amount of water, whether liquid or solid.

There's even a small amount of water vapor on Venus, something like 20 parts-per-million. Fresh Water Without Electricity: Berkey Water Filtration Posted on August 5, by Jaqueline One thing I wish for is that everyone would have clean drinking water available without electricity.

Lessons Learned from a Year without Showering

Water is the most essential source of life on the earth as we need water in every walk of life like drinking, cooking, bathing, washing, growing crops, plants, etc.

We should save water for proper supply of water to future generations without contaminating it. Without rain, there would be no fresh water available, and life would have evolved in a different manner. Humans depend on fresh water for survival. While it is possible to remove salt from ocean water through a process called desalinization, it is expensive, and the cost of transporting water .
