Is there such thing as wasting water?

Yes. A lot of people are deprived of clean and purified drinking water. Americans we use up to 2 gallons of water to do a simple task such as brushing our teeth. This amount of 2 gallons is how much water someone in Africa can use in one whole day. I hope this helps you understand why wasting water is a very real thing

The investiture controversy began as a power struggle between pope gregory vii (1072–85) and henry iv, holy roman emperor (1056–1106).[2] a brief but significant struggle over investiture also occurred between henry i of england and pope paschal ii in the years 1103 to 1107, and the issue played a minor role in the struggles between church and state in france, as well.by undercutting the imperial power established by the salian emperors, the controversy led to nearly 50 years of civil war in germany, and the triumph of the great dukes and abbots. imperial power was finally re-established under the hohenstaufen dynasty. historian norman cantor:
