ARE THE "WATER WARS" COMING?
OF COURSE, THEY WILL COME, UNLESS URGENT MEASURES ARE TAKEN TO IMPROVE WATER USE AND SAVE WATER Only a lazy person does not speak about the imminent water shortage and the upcoming "water crisis". And most people perceive this kind of conversation as an inappropriate joke. What is the "water crisis", what is the water shortage? Yes, look-how much it is around! In rivers and lakes... In the rain and snow... In rowing channels and swimming pools... In process pipelines of enterprises and agricultural irrigation channels... And the world map - which is mostly blue in color-is mostly made up of oceans and seas...
