Water is important because it is one of the best solvents in nature. Living systems require solvents in order to mix various chemicals with one another, and water is the best substance for the job. According to Public Broadcasting Systems, living organisms need water because the biochemical processes of life must take place in a fluid.
Water is a good solvent in part because it is a polar molecule. According to WorldofMolecules.com, this means that polar and ionic substances, such as salt, readily dissolve in water. Water's properties as a solvent allow it to promote life because rather than having to transport solid materials, organisms can dissolve metabolites and nutrients in water, allowing them to move more easily through the body. Many organisms use water to flush toxins and poisonous by-products from their bodies as well. Water also facilitates the bending of enzymes, allowing them to produce necessary chemical reactions within the body quickly.
Water is also an important component of temperature control for animals and it is useful for transporting dissolved substances, according to HowStuffWorks.com. Moreover, water is necessary to sustain life on a larger scale as well. It allows humans to grow crops, raise livestock, travel and power factories. Because it exists in solid and gaseous forms as well as liquid, the environment is able to store water as ice and water vapor, making it readily available

Water is Life
Water is essential to survival. Unlike oil, there are no substitutes. But today, fresh water resources are stretched thin. Population growth will make the problem worse. So will climate change. As the global economy grows, so will its thirst.
This is not an issue of rich or poor, north or south.
The water system of Lake Chad, in central Africa , supports some 30 million people. Yet over the past 30 years, it has shrunk to one-tenth of its former size, thanks to drought, climate change, mismanagement and over-use. Visiting Brazil this fall, I had to cancel a trip down a major tributary of the Amazon. It had dried up.
I have spent the past year beating the drum on climate change. We've seen the results in the “Bali Roadmap,” which charts a course for negotiations on a legally binding treaty limiting greenhouse gas emissions to take over when the Kyoto Protocol expires in 2012. This year, I will make a similar effort to raise public awareness about the Millennium Development Goals.
This September, I will gather top-level officials from across the world at a summit in New York on how to reach the Goals, particularly in Africa . In the meantime, we need to begin thinking about better strategies for managing water—for using it efficiently and sharing it fairly. This means partnerships involving not just governments but civil society groups, individuals and businesses.
We are at the early stages of this awakening. But there are some encouraging signs, especially in the private sector. Corporations have long been viewed as culprits. The smokestacks from power plants pollute our air, the effluents from industry spoil our rivers. But this is changing. More and more today, businesses are working to become part of the solution, rather than the problem.
The main theme: moving beyond the mere use of water to stewardship. This translates into a commitment to engage with the United Nations, governments and civil groups to protect what is becoming an increasingly scarce resource and ensure that local communities benefit.
Every journey is comprised of myriad small steps, and they spoke about those, too. A major textiles company told how it was working with local governments and farmers to conserve watersheds in growing cotton. A jeans designer is planning to change its labels, calling for washing in cold and hanging dry as a step to save water.
A drop in the bucket, yes. But I see it as the first wave in a tide of change.
Hope it helps u!!
