but the amount of water on Earth will always remain essentially constant. Water scarcity arises when the various forms of fresh water become less common or harder to access, and some parts of the world (like arid desert climates) find it difficult to locate long term water sources because of...

Could it be that people had simply lost their understanding for astronomy, physics, natural behaviour: the understanding of the language spo- ken by the cosmic clock of the zodiac signs, the sun, the moon, the stars, which is essential and funda- mental for the seasonal stellar orientation ...
