No cities on the moon—there isn't enough water, scientists say

• The article states that there is no city on the moon, and the lack of sufficient water makes establishing permanent settlements impractical.
• Scientists claim that the moon has about 1 billion tons of water, but without recycling, a city of 1 million people would run out of water in just over a century.
• The study suggests that while power is available due to the permanent sunlight in craters, water scarcity remains a major obstacle to sustainable moon settlement.

• The article highlights that the moon's poles contain water ice in cold traps, but the amount is insufficient for large-scale human habitation.
• The study notes that even with 98% efficient water recycling, a city of 1 million people would still deplete its water supply within a few decades.
• The researchers propose potential solutions, such as improving water recycling, using vertical farming, or importing water from asteroids, but these are not yet feasible.

• The article emphasizes that while the moon has water, the quantity is not enough to support a large population without relying on Earth for resources.
• The study concludes that without significant advancements in water management and technology, establishing a sustainable lunar colony is unlikely in the near future.
• The findings suggest that while the moon has water, it is not enough to support a thriving human community without additional resources or technological breakthroughs.
