Se puede decir que la tierra es un planeta de Agua, porque el agua cubre alrededor de un 70% de la superficie terrestre.
Por otra parte, sabemos que el agua, llamada por muchos el '' vital líquido'' es primordial para el desarrollo de la vida.Si relacionamos la anterior afirmación con la vida humana vamos a ver en este post como el agua es un recurso mas bien limitado.

The earth can be said to be a Water planet, because water covers about 70% of the earth's surface.
On the other hand, we know that water, called by many the '' vital liquid '' is essential for the development of life.If we relate the previous statement with human life we will see in this post how water is a rather limited resource.
Indeed, 97% of the planet's water is found in the oceans and we know that it has a high concentration of salts and therefore cannot be used directly for human consumption, unless it is subjected to desalination, a process that has a high cost in energy and other inputs and is expensive for the consumer.
Desalinated water currently accounts for only 1% of human consumption. The countries that have developed this process the most are Israel, Saudi Arabia, Spain, India, China, Australia, USA and Chile.
We can already deduce that only 3% of the Earth's water is fresh water, suitable for human consumption and yet this low percentage is not fully within the reach of the population for several reasons:
