Importance of water
We can start by saying that water is one of the natural elements found in greater quantity on planet Earth.
In addition, we can add that water is one of those items that most directly relate to the possibility of the development of different forms of life. Similarly as with oxygen, water is essential for both plants and animals, humans and all known life forms may exist. It is important to note that the bodies all living things are made in a high proportion of water, being that this is the making up the muscles, organs and different tissues. Thus, the water becomes a very important element for the existence of life.
According to the United States Geological Survey (USGS for its acronym in English), the surface of our planet is made up three-quarters of water, ie 71%. This percentage 96% are oceans and seas, while the rest called "freshwater" for not having salt concentrations exists in the atmosphere as water vapor, rivers, lakes, at the poles, glaciers, in soil moisture and groundwater, and even in living beings.
But water is not only important for human consumption but also has to do with allowing the existence of a complex number of living beings. First, water is one of the most important food plants, so water coming through irrigation or rain is responsible for growing all kinds of plants and vegetation that exists in the planet. On the other hand, water is consumed by animals and then also serves as a natural element vital for their development.
An essential element, and protagonist of the origin of life
Although certain organisms need to consume more than others, we all need water to survive and in fact, it is known that without it life on Earth would never have begun. As a medium in which organic compounds can be mixed together, water facilitated the generation of the early life of the planet, possibly provide protection from solar radiation.
From these first organisms to the most complex plants and animals, water has played a key role in the beginnings of life. In humans it acts both as solvent and as a mechanism that carries the essential vitamins and nutrients from food into cells. In addition, our bodies also use this resource to eliminate toxins, regulate
Take care of this resource that belongs to all
Protection of water reserves available on the planet is then an action that all countries, governments and communities should seek to ensure that these natural waterways allow the survival not only of human beings if not any life form known .
The amaneza of global warming and human responsibility
Due to global warming, now in many parts of the world the demands of this vital liquid can not be satisfied. Experts from the Department of Economic and Social Affairs of the UN say about 1.2 trillion people have no access to drinking water and are forced to travel long distances to find and meet their most basic needs.
The water is so significant in our lives, which has been declared a fundamental right for humans. It is our duty to properly use and care, to prevent this non-renewable resource continue running.
