The system that moves water around the Earth is off balance for the first time in human history. ... The report calculates that, on average, people need a minimum of about 4,000 liters (just over ...
Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
A mere 0.014% of all water on Earth is both fresh and easily accessible. [35] Of the remaining water, 97% is saline, and a little less than 3% is difficult to access. The fresh water available to us on the planet is around 1% of the total water on earth. [36] The total amount of easily accessible freshwater on Earth is 14,000 cubic kilometers.
Water can be conserved by not allowing freshwater to be used to irrigate luxuries such as golf courses. Luxury goods should not be produced in areas where freshwater has been depleted. For example, 1,500 liters of water is used on average for the manufacturing of a single computer and monitor. [52]

In other words, by 2050 at the latest, Californians would lose access to a volume of water that is enough to supply 50-90% of all the state’s households — or to irrigate 17-33% of all the ...
Earth's approximate water volume (the total water supply of the world) is 1.386 billion cubic kilometres (333 million cubic miles). [24] Liquid water is found in bodies of water, such as an ocean, sea, lake, river, stream, canal, pond, or puddle. The majority of water on Earth is seawater. Water is also present in the atmosphere in solid ...
