The human race depends on water for a variety of things. It is used in our hygiene, helps the body to maintain a constant temperature, flushes unwanted items from our systems, and of course provides us with many recreational activities, from swimming to water balloon fights. Indirectly, we are dependent on water because it allows vegetation to grow and animals to live. Without water, there would be no us. For this reason, water has a bond to the human race.
Water also has a bond to the land.
It allows plants to grow. In fact, without water, try to get something to grow. You will probably end up with a beautifully dry, yellow looking plant. Many beautiful things like flowers, green grass, and tall trees would be nonexistent without water. Like humans, these living things are also dependent on water.
