Should you’re in search of an indication of the Finish Instances, right here’s one: Las Vegas, town the place seemingly something and every thing is condoned, has made grass — the decorative type — unlawful.
A lot of the West is experiencing the worst drought in a long time, a “megadrought” that has kindled early wildfires and extreme water shortages — and the seasonal warmth has hardly begun. “There’s a 100% probability that it will get worse earlier than it will get higher,” Daniel Swain, a local weather scientist on the College of California, Los Angeles, tells the graphics editor Nadja Popovich in The Instances right this moment. “We have now the entire lengthy, dry summer season to get by way of.”
Lake Mead, which sits on the Colorado River (behind the Hoover Dam) and supplies 90 p.c of the water provide for Las Vegas and southern Nevada, this week reached its lowest capability since its creation within the Thirties. And several other states that draw their water, in strict allotments, from the Colorado River should take up stark restrictions on its use in cities and for farming.
“We’re type of at an existential level proper now within the West,” stated Kyle Roerink, govt director of the nonprofit Nice Basin Water Community, in a telephone dialog. “Even fundamental terminology that when was a given — now we’re seeing a shift within the nomenclature towards saying, effectively, we’re not in a interval of drought, we’re in a interval of aridification.”
Enter aridification, exit grass. Gov. Steve Sisolak of Nevada simply signed into regulation bill AB356, which requires the removal of all “nonfunctional turf” from the Las Vegas Valley by the year 2027. The effort will conserve about 10 percent of the region’s annual allotment of water from the Colorado River. “It’s a really good time to have put forth something like this,” said Mr. Roerink, whose organization was part of a bipartisan coalition, including the Southern Nevada Home Builders Association, that supported the bill.
The Southern Nevada Water Authority has not yet formed the committee that will actually define “nonfunctional turf.” For now, the category loosely describes the few thousand acres of grass carpeting the region’s street meridians, office parks and housing developments, and amounts to roughly one-third of all the grass in the region.
“The best way to describe it is, it’s the type of grass that’s only used when someone is pushing a lawn mower over it,” Mr. Roerink said. “Other shorthand that became commonspeak during this legislative session was ‘useless grass.’” (That other ostensibly useful grass — at parks, schools, golf courses and single-family lawns — is still allowed, at least for now.)
“Nonfunctional turf” — the very phrase is an existential knot. Is it redundant, or an oxymoron? Either way, it perfectly encapsulates our contorted relationship to nature: Some grass is good, some grass is bad, and all of it (except the kind that grows wild in meadows) is engineered and curated by us.
The challenge isn’t excess grass so much as excess people. Southern Nevada has had explosive growth in recent years, and water usage has increased by more than 9 percent since 2018. Eliminating “useless” grass was a good first step, Mr. Roerink said, but he worried that the water savings would simply be translated into an argument for new development (doubtless with more useful grass).
“What are the Mojave Desert’s limits?” he said. “You know, in some of the areas where Vegas wants to develop is desert tortoise habitat, and there’s not a lot of good desert tortoise habitat left. What’s the future of that going to be?”
The fundamental question is: What counts as a “functional” or non-useless species? Humanity seems dead-set on finding out. We have a knack for seeking out the harshest environments and trying to plant ourselves there, from the Amazon to Antarctica. Lately it’s outer space, with Mars as the ultimate destination. On Monday the billionaire entrepreneur Jeff Bezos announced that he would soon be venturing into orbit, beating the billionaire entrepreneur Elon Musk to the punch (unless the billionaire entrepreneur Richard Branson gets there even sooner).
It bears noting that Mars has no grass, functional or otherwise, nor discernible life of any kind. (Earth’s deserts, including the Mojave, are where Mars rovers go for practice.) If Martian colonists are fortunate, they might dig up something akin to the microscopic, multicellular rotifers that scientists recently retrieved from Siberian permafrost. The tiny animals — resistant to radiation, extreme acidity, starvation, low oxygen and dehydration — had been effectively frozen for 24,000 years, yet they bounced right back to life and began to multiply.
“They’re the world’s most resistant animal to just about any form of torture,” Matthew Meselson, a molecular biologist at Harvard, told The Times. “They’re probably the only animals we know that could do pretty well in outer space.”
The last time the rotifers were up and about, woolly mammoths roamed the planet, including in what is now the Las Vegas Valley. To the extent that mammoths thought anything, they probably held very strong opinions about who was and was not a “functional” species. Alas, we’ll never know.

Science in The Times, 90 years ago today
MALINTA, Ohio — A terrific shock jarred six Ohio counties today, rocked houses in dozens of towns in this state and Indiana and roused thousands of sleeping persons. Tonight the crowds of people who came to Malinta as the center of the shock were mystified as to whether it was caused by an explosion or by the fall of a giant meteor.
Sensing that something far out of the ordinary had happened, hordes of motorists drove from many places to find out the cause. A strange hole, half a mile from Malinta on State Route 109 was the focus of the crowd. …
