Answer:
WITHOUT WATER NO LIFE – MANKIND KNEW THIS ALREADY SINCE PREHISTORIC TIMES. MANY RITES
AND CUSTOMS, BUTALSO TECHNICAL PLANTS FROM THE DIFFERENT CULTURES GIVE EVIDENCE FOR
THE INDISPENSABILITY OF WATER, BUT ALSO FOR THE DANGERS CONNECTED WITH WATER IN ITS
DIFFE-RENT FORMS OF APPEARANCE. THE DEVELOPMENT OF THE BRANCHES OF WATER RESEARCH
CORRESPONDS TO THE IMPORTANCE OF WATER. TODAY IT IS WELL KNOWN THAT THE SUBSTANCE
WATER IN ITS SOLID, LIQUID AND GASEOUS PHASE SHOWS PHYSICAL AND CHEMICAL PECULIARITIES.
COMPARED WITH SIMILAR CHEMICAL COMPOUNDS ONLY WATER HAS SUCH ANOMALIES. WITHOUT THESE
THE OCEANS, THE GLOBAL ENERGY AND MATERIAL CYCLES AS WELL AS THE CONTINENTS WITH THEIR
VEGETATION, LAKES, RIVERS AND SO ON INCLUDING MANY ATMOSPHERIC PROCESSES COULD NOT EXIST
AS WE KNOW THEM. WATER IS THE PREREQUISITE OF LIFE AND OUR CIVILIZATION. THE ORIGIN OF ANY
WATER SUPPLY FOR MAN IS THE GLOBAL WATER CYCLE WITH ITS MANIFOLD COUPLINGS TO WEATHER
AND CLIMATE AS WELL AS TO NATURE
