To help Bruno there is Lorenzo, always ready to intervene in the various tasks of the family business.
Nothis is destroyed, but everything is transformed: the society of re-use.
Water is a primary good. The survival of man and all the species that inhabit the planet depends on this good. It is not a coincidence that in ancient times the first civilisations arose in proximity of lakes and rivers or in coastal areas that guaranteed the access to the water resources and all the linked goods. From the exploitation of freshwater and saltwater depends, in fact, also the economic chances of man that exploits the fish potential for commercial purposes. But the thrifty uses of this resource involve the primary sectors like agriculture and breeding, as well as the processes of industrial transformation of many products: the realisation of clothes, the furnishing of the houses, offices and so on.
In addition to this, water turns out to be a fundamental element in the daily care, personal and surroundings cleanliness, in the hydration of the body. Without it, we couldn’t survive. Water is an essential good. The importance that it arouses recalls the power it has. Geopolitics is influenced by its presence or absence. The economic and politic interests determine its distribution, the availability on the part of the populations.
The importance of the water purification systems.
The evolved societies are equipped with complex water purification systems. Big cities have them to filter the so-called wastewater, waters that come from the citizen uses and that before being put into the environment require a purification. They are the waters from the sewer and the ones consequent the industrial processing. Their purification allows the removal of the contaminants present and the elimination of possible organic and inorganic pollutants from which water is contaminated.
The water purification systems preserve and safeguard the environment from pollution; at the same time, mostly on the agricultural branch, in some cases satisfy the demand linked to the re-use of the resources once purified, mostly in drought settings, where the hydric resources are limited.
Yes to recycle, no to throw-away.
Recycling as much as possible and with the maximum efficiency is a necessity, in the dry areas of the planet and even more in the ones economically disadvantaged.
That’s what is told by the lives of Bruno and Lorenzo, forced in a rural reality where every millimetre of water is precious for the personal survival and for the survival of the business activity. Their society is one of the re-use, where science and technique are committed in the development of cutting-edge water purification systems, environmental friendly and economically sustainable, also for the disadvantaged communities as theirs.
Metaphors aside, beyond fiction, the major challenge is once again about education, awareness of environmental issues, the protection of the environment that hosts man, the conscious and intelligent use of present resources that are not infinite. Politics must thus be challenged by science in order to contribute, together, in the framework of a joint effort, to the construction of a society accustomed to saving, to the detriment of less virtuous practices, of disposable, waste and waste.
