Las Vegas has a hard won reputation as the gamblers' paradise. The multitude of glitzy casinos do their best to entice the multitude of tourists to risk their dollars in a variety of games.
But Las Vegas is a synthetic city in the Nevada desert. It has developed behind nothing more than the common lust to make money the easy way. However, even such edifices cannot operate without an adequate continuing supply of water. The Hoover Dam was built on the Colorado River as a make work activity during the Great Depression. This created Lake Mead which provided the source for the water essential for the construction, operation and maintenance of all the infrastructure, including the multitude of casinos, of Las Vegas as well as the needs of the populace.
But the authorities got their sums wrong! If the water out exceeds the water in then the container will empty and then the water out will dry up. That is what is happening to Lake Mead and panic is setting in amongst the authorities and citizens of Las Vegas. It is ironical that the sponsors of Las Vegas gambled and are now losing much more than those who have been enticed there by the false promise of easy money.
Of course, Las Vegas is only an example of the muddled thinking of Homo sapiens that has resulted in the intractable devastation of Planet Earth for the sake of the illusory wants of some of the global population.
