Is any panic more primitive than the one prompted by the thought of empty grocery store shelves? Is any relief more primitive than the one provided by comfort food?

Most everyone has been doing more cooking these days, more documenting of the cooking, and more thinking about food in general. The combination of meat shortages and President Trump’s decision to order slaughterhouses open despite the protestations of endangered workers has inspired many Americans to consider just how essential meat is.

Is it more essential than the lives of the working poor who labor to produce it? It seems so. An astonishing six out of 10 counties that the White House itself identified as coronavirus hot spots are home to the very slaughterhouses the president ordered open.

In Sioux Falls, S.D., the Smithfield pork plant, which produces some 5 percent of the country’s pork, is one of the largest hot spots in the nation. A Tyson plant in Perry, Iowa, had 730 cases of the coronavirus — nearly 60 percent of its employees. At another Tyson plant, in Waterloo, Iowa, there were 1,031 reported cases among about 2,800 workers.

Despite this grisly reality — and the widely reported effects of the factory-farm industry on America’s lands, communities, animals and human health long before this pandemic hit — only around half of Americans say they are trying to reduce their meat consumption. Meat is embedded in our culture and personal histories in ways that matter too much, from the Thanksgiving turkey to the ballpark hot dog. Meat comes with uniquely wonderful smells and tastes, with satisfactions that can almost feel like home itself. And what, if not the feeling of home, is essential?

Animal agriculture is now recognized as a leading cause of global warming. According to The Economist, a quarter of Americans between the ages of 25 and 34 say they are vegetarians or vegans, which is perhaps one reason sales of plant-based “meats” have skyrocketed, with Impossible and Beyond Burgers available everywhere from Whole Foods to White Castle.

At the very least it has forced us to look. When it comes to a subject as inconvenient as meat, it is tempting to pretend unambiguous science is advocacy, to find solace in exceptions that could never be scaled and to speak about our world as if it were theoretical.

According to the research director of Project Drawdown — a nonprofit organization dedicated to modeling solutions to address climate change — eating a plant-based diet is “the most important contribution every individual can make to reversing global warming.”

We cannot claim to care about the humane treatment of animals while continuing to eat meat regularly. The farming system we rely on is woven through with misery. Modern chickens have been so genetically modified that their very bodies have become prisons of pain even if we open their cages. Turkeys are bred to be so obese that they are incapable of reproducing without artificial insemination. Mother cows have their calves ripped from them before weaning, resulting in acute distress we can hear in their wails and empirically measure through the cortisol in their bodies.

No label or certification can avoid these kinds of cruelty. We don’t need any animal rights activist waving a finger at us. We don’t need to be convinced of anything we don’t already know. We need to listen to ourselves.

It goes without saying that we want to be safe. We know how to make ourselves safer. But wanting and knowing are not enough.

These are not my or anyone’s opinions, despite a tendency to publish this information in opinion sections. And the answers to the most common responses raised by any serious questioning of animal agriculture aren’t opinions.

Don’t we need animal protein? No.

We can live longer, healthier lives without it. Most American adults eat roughly twice the recommended intake of protein — including vegetarians, who consume 70 percent more than they need. People who eat diets high in animal protein are more likely to die of heart disease, diabetes and kidney failure. Of course, meat, like cake, can be part of a healthy diet. But no sound nutritionist would recommend eating cake too often.

If we let the factory-farm system collapse, won’t farmers suffer? No.

The corporations that speak in their name while exploiting them will. There are fewer American farmers today than there were during the Civil War, despite America’s population being nearly 11 times greater. This is not an accident, but a business model. The ultimate dream of the animal-agriculture industrial complex is for “farms” to be fully automated. Transitioning toward plant-based foods and sustainable farming practices would create many more jobs than it would end.

Don’t take my word for it. Ask a farmer if he or she would be happy to see the end of factory farming.

A 2015 study found that a vegetarian diet is $750 a year cheaper than a meat-based diet. People of color disproportionately self-identify as vegetarian and disproportionately are victims of factory farming’s brutality. The slaughterhouse employees currently being put at risk to satisfy our taste for meat are overwhelmingly brown and black. Suggesting that a cheaper, healthier, less exploitative way of farming is elitist is in fact a piece of industry propaganda.

Can’t we work with factory-farming corporations to improve the food system? No.

Well, unless you believe that those made powerful through exploitation will voluntarily destroy the vehicles that have granted them spectacular wealth. Factory farming is to actual farming what criminal monopolies are to entrepreneurship. If for a single year the government removed its $38-billion-plus in props and bailouts, and required meat and dairy corporations to play by normal capitalist rules, it would destroy them forever. The industry could not survive in the free market.

Perhaps more than any other food, meat inspires both comfort and discomfort. That can make it difficult to act on what we know and want. Can we really displace meat from the center of our plates? This is the question that brings us to the threshold of the impossible. On the other side is the inevitable.

With the horror of pandemic pressing from behind, and the new questioning of what is essential, we can now see the door that was always there. As in a dream where our homes have rooms unknown to our waking selves, we can sense there is a better way of eating, a life closer to our values. On the other side is not something new, but something that calls from the past — a world in which farmers were not myths, tortured bodies were not food and the planet was not the bill at the end of the meal.

One meal in front of the other, it’s time to cross the threshold. On the other side is home.
