Water creates so many wonderful things. Its a great source of recreation with everything from surfing to swimming, to model boat racing. Water can be used to generate electricity from a hyrdoelectric dam or even used to create a fuel whose waste product is oxygen. Most importantly it allows life to flourish. However, simply having too much water is incredibly dangerous. Think of floods and tsunamis. When I was a kid I almost drowned in a wave pool at an amusement park. Luckily a lifeguard rescued me from the water.
