Hola amigo @emiliomoron
I have been able to read in some opportunities that water scarcity will be the main cause of war in the future, and I don't doubt it. More considering that water sources are being affected by the severe climate changes. It is a very complex situation.
So the best thing to do is to try to make water last as long as possible, for future generations.
That's right my friend, with climate change and the contamination of water bodies we are undoubtedly laying the groundwork for a future conflict over water reserves, it is necessary for the future that we take care of water.
