Water is a precious resource that nature has bestowed on Planet Earth. Water is vital for all life forms as also for all vegetation. Terrestrial life forms need water to drink. If they do not get water to drink, they will perish. All aquatic creatures need water bodies to live in. Whether they are rivers or seas, or oceans, water bodies are their habitat. Vegetation needs water to survive. All vegetation will wither and die in the absence of water. Water is, therefore, an important resource that must be saved. We must not use wastewater. We must use water judiciously.
