Answer 1

We couldn't live without it.  The human body ranges from 55 to 78% water.

"Clean, fresh drinking water is essential to human and other life. However, in many parts of the world - especially developing countries - there is a water crisis, and it is estimated that by 2025 more than half of the world population will be facing water-based vulnerability. Water plays an important role in the world economy, as it functions as a solvent for a wide variety of chemical substances and facilitates industrial cooling and transportation. Approximately 70% of freshwater is consumed by agriculture.

All the major components in cells (proteins, DNA and polysaccharides) are also dissolved in water.  

The existence of liquid water, and to a lesser extent its gaseous and solid forms, on Earth is vital to the existence of life on Earth as we know it. The Earth is located in the habitable zone of the solar system; if it were slightly closer to or further from the Sun (about 5%, or 8 million kilometres or so), the conditions which allow the three forms to be present simultaneously would be far less likely to exist."
