1 . Las Vegas city in Nevada is built in a desert. The city may be known to the world for its partying. But officials have found that there are 21 square kilometers of useless grass. The grass is never laid on, played on or even stepped on. The grass is only there to look nice.
Now, the city is asking the Nevada state legislature (立法机构) to ban useless grass. It is trying to become the first place in America to ban that kind of grass often seen between streets, in housing developments and in office parks.
Useless grass nearly makes up 40% of all the grass in Las Vegas and it needs lots of water to survive. Grass needs four times more water than dry climate plants. By tearing out the grass, the city could reduce yearly water usage by 15%.
In 2003, the Southern Nevada Water Authority banned developers from planting grass in front of new homes. It also offered homeowners $30 for each square meter of grass they tear out. But fewer people are now using the program. Water usage has increased here by 9% since 2019. And last year, Las Vegas set a record of 240 days without major rainfall. The Colorado River provides much of Nevada’s drinking water. The river could lose more water as climate change affects it.
Water officials in other dry cities said water usage needs to be reduced. But they fear the reaction to reforms like the ones in Las Vegas if their communities do not accept them. Cynthia Campbell is the water resources adviser for the city of Phoenix in Arizona. “The city restrictions (限制) may get too hard for some residents (居民). They’ll say that is the point of no return for them,” Campbell said. “For some people, it’s a pool. For some people, it’s grass.”
