Water is the most important natural resource in the world since without it life cannot exist and most industries could not operate. Although human life can exist for many days without food, the absence of water for only a few days has fatal consequences.
The presence of a safe and reliable source of water is thus an essential prerequisite for the establishment of a stable community. This means that the importance of water as a natural resource that requires careful management and conservation must be universally recognized.
Although nature often has great ability to recover from environmental damage, the growing demands on water resources necessitate the professional application of fundamental knowledge about the water cycle to ensure the maintenance of quality and quantity.
