Where the Grass is Greener, Except When Its Nonfunctional Turf – The New York Times

If youre looking for a sign of the End Times, heres one: Las Vegas, the city where seemingly anything and everything is condoned, has made grass the ornamental kind illegal.

Much of the West is experiencing the worst drought in decades, a megadrought that has kindled early wildfires and severe water shortages and the seasonal heat has hardly begun. Theres a 100 percent chance that it gets worse before it gets better, Daniel Swain, a climate scientist at the University of California, Los Angeles, tells the graphics editor Nadja Popovich in The Times today. We have the whole long, dry summer to get through.

Lake Mead, which sits on the Colorado River (behind the Hoover Dam) and provides 90 percent of the water supply for Las Vegas and southern Nevada, this week reached its lowest capacity since its creation in the 1930s. And several states that draw their water, in strict allotments, from the Colorado River must absorb stark restrictions on its use in cities and for farming.

Were kind of at an existential point right now in the West, said Kyle Roerink, executive director of the nonprofit Great Basin Water Network, in a phone conversation. Even basic terminology that once was a given now were seeing a shift in the nomenclature toward saying, well, were not in a period of drought, were in a period of aridification.

Enter aridification, exit grass. Gov. Steve Sisolak of Nevada just signed into law 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 regions annual allotment of water from the Colorado River. Its 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 regions 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, its the type of grass thats 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 isnt 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 Deserts limits? he said. You know, in some of the areas where Vegas wants to develop is desert tortoise habitat, and theres not a lot of good desert tortoise habitat left. Whats 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 its outer space, with Mars as the ultimate destination. On Monday the billionaire entrepreneur Jeff Bezos announced that he would soon be venturing into space, 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. (Earths 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.

Theyre the worlds most resistant animal to just about any form of torture, Matthew Meselson, a molecular biologist at Harvard, told The Times. Theyre 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, well 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.
