Highlights: Last month, an environmental group sued the federal government for failing to protect turtles from cows.

To understand this bizarre-sounding but important lawsuit, you first have to understand the nature of cattle ranching in the American West.

Some 215 million acres of public land in the West — over 10 percent of the continental US — is loaned to ranchers at bargain-bin prices for their cattle to graze. As the cattle graze, they tend to disrupt ecosystems and do a lot of damage to the land. They eat or destroy plants consumed by native species, like turtles, which can lead to biodiversity loss. Their manure pollutes rivers and streams, and as they move about, they erode soil.

WWP alleges that for decades, the US Bureau of Land Management (BLM) and other agencies have violated an agreement they signed in 2001 that forbids cattle grazing in a part of Nevada’s Gold Butte National Monument in order to protect the desert tortoise, whose population has plunged since the 1980s.

One of the people accused of illegally grazing cattle on this protected land happens to be Cliven Bundy, the far-right cattle rancher who made a name for himself in 2014 after an armed confrontation with hundreds of his supporters against the BLM (the agency stood down and has allowed Bundy to continue illegally grazing his cattle).

BLM is generally mandated by federal law to assess the environmental health of grazing land before it renews ranchers’ permits, but Molvar said the agency often fails to do so, resulting in widespread environmental degradation.

BLM doesn’t face any real consequences because for years, Congress has passed a rider that requires BLM to renew cattle grazing permits upon their expiration, with or without the required environmental analysis.

The market rate for private grazing land in the Western US was around $22.60 per animal unit per month (AUM) in 2019, but in that same year, the BLM charged ranchers just $1.35 per AUM.

Even worse, the federal government spends millions annually on its “Wildlife Services” division, which kills wild animals it deems a threat to grazing livestock. Last year, it racked up a body count of 1.75 million animals, or 200 per hour.

The federal government’s livestock grazing program is just one part of America’s agricultural land use story. The other part is all the land used to grow crops to feed farmed cattle, chickens, pigs, and fish, which comes in at 127 million acres.

All told, a staggering 41 percent of land in the continental US is used for meat, dairy, and egg production. Globally, it’s more than one-third of habitable land. Much of it was once forest that’s since been cut down to graze livestock and grow the corn and soy that feeds them.

To avoid the worst effects of climate change, it won’t be enough to just reduce the amount of greenhouse gasses we spew into the air — we also need to remove them from the atmosphere. One effective way to do that, which doesn’t rely on unproven carbon capture technology, is by “rewilding,” or retiring agricultural land back to its original ecosystem so that its vegetation can sequester carbon dioxide. Much of that potential is currently wasted on inefficient livestock production — what climate scientists call the “carbon opportunity cost” of meat.
