The book is in the vein of going to outline the characteristics of "planet water" while taking a different view of the whole. Instead of delving into only one particular aspect (the scientific-technological or the social, for example), it was preferred to consider all the links that water has to man and society, going on to outline a series of "journeys," each corresponding to each of the seven chapters that form the structure of the writing. Very briefly, these different and complementary points of view can be summarized in this outline: The indissoluble link between water and life, from the Universe to our Planet to the biosphere and our cells. The chemical and physical properties of water, what they depend on and what influences they have in defining the importance of this molecule. Water-related phenomena such as the water cycle, geology, types of water, and everything related to the morphology of planet Earth. What uses, how much consumption and treatments are related to water to understand the numbers, purposes and quality of water used. What are the social aspects related to water from historical, economic and political aspects to all forms of artistic expression and daily life. How we are attacking water through pollutions of various kinds, the problem of global warming, and waste related to today's society. The concept of water rights, the scarcity of water resources with related inequalities, the confrontation-clash between market vision and essential human rights. The beginning and the end of the book constitute the central themes around which all the arguments unfold. The link to life and the right to water are two sides of the same coin that will lead to very precise and detailed conclusions, such as the awareness of a new sustainable model of development, the necessary actions to combat global problems such as pollution, global warming and water scarcity, and the conviction that rights and life are more important and necessary than purely economic iss
