The Importance of Water
Water is one of the most important things on earth. Every living thing needs water to survive. Without water, plants, animals , microbes - all perish.
Our bodies are made of a 75 % water . So we are literally walking bags of water. The water allows the blood through the blood vessels supplying the vital nutrients and body flows. Water also allows the waste material is eliminated from the body through the excretory system . Our need for water is most evident when we are thirsty . The taste of the water that flows through the gorge is something that we all found so much pleasure in. We drink cups of this daily beautiful clear liquid. It is essential to our lives.
The first human civilizations began near rivers . The Nile, the Tigris and Euphrates was where the man began to colonize the land. Throughout the world, major rivers have played an important role in the evolution of man.
The water is used for drinking, washing , cleaning and almost all activities that do not care . Without water , life is impossible.
Water covers about two-thirds of the total land area. The vast expanse of the seas and oceans has long been our main source of food and transportation . Millions of fish in the Sea. They provide abundant food. Most of us have eaten fish , except those who do not eat meat. Most of humanity will continue to eat fish .
Rivers, seas and oceans provide man with an important means of travel. In ancient times , men explored the land around the Sea. British , Portuguese, Spanish, Dutch and others all came to less developed world in their ships. Conquered or colonized what they found . Much of what we today are influenced by travelers who have passed through the seas on board a long time ago .
Today, rivers of the world are of great importance for humanity. Huge oil, container and other ply these routes. In fact, many shipping routes are overcrowded .
When water is scarce , such as when there is a drought , when we know how terrible consequences may be . Plants, animals and human beings perish. The affected land becomes barren and dry. Nothing grows . In the middle of the Sahara desert , where there is little rain, it is also very little life. In particular, we sand and more sand. No man can live .
People living near or around deserts know the value of water. They know how important it is and they are very careful to use it. We who live in a country where water is abundant , think nothing standing in the shower for an hour and a half. Those who live in arid areas do not have that luxury. They can not afford to waste water as we do .
