Micro organisms can :
spoil and damage the food,
change the taste of food,

Water is essential, you can only survive an average of 3 days without it. (some people have survived for longer though.)
Water is important for shipping and trade, because, ships. They go across water. Trade happens. It's hard to fit a lot in airplanes and you have to monitor it's weight slowly. Across land, it's also hard to fit a lot in random trucks driving across what was an ocean. (it would also be much more tedious) It's also one of the cheapest ways.
