There's fun food technology, like meal and grocery delivery, and then there's urgent food technology: the kind that can address the looming questions of how we're going to feed 9.7 billion people by 2050, and how we're going to do that without worsening the climate crisis.

This might sound like it would require radically more efficient crops—a new green revolution. Or maybe it will require a new type of fertilizer, a crazy advance in nanotechnology, or something involving interstellar farming. Paging Elon Musk!

WIRED OPINION About Bruce Friedrich is executive director of The Good Food Institute, a nonprofit organization that promotes alternatives to animal-based meat, dairy, and eggs.

But no, in fact the solution to both of the big problems in food technology—how we're going to feed a burgeoning population and what we're going to do about climate change—is actually pretty simple: plant-based protein.

At least that's what Alphabet CEO Eric Schmidt claimed at the Milken Global Summit a few months ago. He calls the concept "nerds over cattle," and it's the reason that the Good Food Institute, which I direct, exists: to promote plant-based and "clean meat" technologies, to solve the problems of animal agriculture and improve life on earth by an order of magnitude in the near future.

Plant-based meat is obvious: It's meat made from plants. Clean meat is less obvious; it's meat grown through cellular agriculture in what look like meat breweries, no animal slaughter required.

There are myriad problems of animal agriculture, but the two that most people in agricultural technology are most worried about are climate change and sustainability.

Animal agriculture is an inordinate contributor to climate change. United Nations scientists have written that animal agriculture contributes about 40 percent more to climate change than all of the planes, trucks, cars, and other forms of transportation combined. Scientists from the World Bank and International Finance Corporation, writing for the Worldwatch Institute, dispute the U.N.'s findings and argue that the number is actually much higher.

Either way, eating chicken is a lot worse for the climate than eating chickpeas. Think about it this way: Of commonly consumed meats, chicken does the least harm to our climate, and yet even chicken causes 40 times more climate change per calorie of protein than the legumes that would otherwise be turned into plant-based meat.

That's a good argument that people who care about the climate should consider shifting their own diets toward more plants and fewer animals, of course. But it's an even bigger argument that governments and foundations that care about our climate should actively support a large-scale shift away from conventional animal agriculture and toward plant-based and clean meat alternatives.

Indeed, the most reputable thinktank in Europe, The Royal Institute of International Affairs (better known as Chatham House), reported that it would be impossible for the governments of the world to meet their Paris Agreement obligations unless their populations consume less meat. So with the ratification of the Paris Agreement by the two biggest greenhouse gas emitters in the world—China and the US—advancing this technology has become all the more critical.

The other reason plant-based companies are being snatched up by global food conglomerates (see: Pinnacle Foods's acquisition of Gardein) and plant-based start-ups have raised hundreds of millions of dollars in the past few years (see: Impossible Foods) is for their basic efficiency; they can deliver protein to the world much more efficiently. To produce just one calorie of meat, it requires a minimum of nine calories of feed crops like corn and wheat, according to the World Resources Institute. Cycling crops through animals is not only vastly inefficient, it also diverts cheap, healthful food away from hungry mouths just to produce a more expensive and less healthful product.

As just one example of the health benefits of a shift away from animals, an Oxford study published in the Proceedings of the National Academy of Sciences earlier this year found that a worldwide shift away from animals and toward plants would decrease premature mortality globally by between 6 and 10 percent, with most of the benefits coming in the developing world.

Of course, eating whole plants would be even less energy intensive than processing those plants into plant-based meat, but in a world that wants to consume more and more meat, plant-based meat and clean meat are an appealing solution.

This improved future is already materializing. Over just the past five years, alternatives to animal products have earned hundreds of millions of dollars in support from some of the world's smartest and most forward-thinking investors, including Bill Gates, Marc Benioff, Sergey Brin, Twitter's co-founders, and Li Ka-shing, one of the richest people in Asia. Impossible Foods, Beyond Meat, and Memphis Meats are among the most successful startups working on meat alternatives. When Bill Gates tried Beyond Meat's plant-based chicken strips, he wrote on his blog: "What I was experiencing was more than a clever meat substitute. It was a taste of the future of food."

A few years back, Google attempted to purchase Impossible Foods, a company founded by Stanford biochemist Pat Brown, who is the founder of the open-access peer-reviewed Public Library of Science (PLoS) journals, reportedly for close to $300 million. Brown and his team are looking at meat at a molecular level and attempting to replicate all aspects of it, using innovative food technologies. Impossible Foods has developed a plant-based product that looks and tastes like ground beef. When my team and I had a private tasting some months before the official launch at David Chang’s Momofuku, one of our scientists who is a long-time vegetarian found it so meat-like that she couldn't eat it.

Considering the Google offer, I have to wonder if Eric Schmidt telegraphed one of the projects being developed in the famously secretive Google-X labs. Regardless, readers needn't wait for Google-X to get a taste of Schmidt’s vision. Superb plant-based meats from Gardein, Tofurky, Boca, Beyond Meat and other established companies are already available in nearly every grocery store.

Quite simply, we're not going to feed the world, and we're not going to avoid a climate catastrophe, if we continue our global reliance on a system of food production that is so vastly inefficient and polluting. Individual change is important, but institutional change is even more important, and a shift away from conventionally created meat and toward plant-based and clean meat alternatives should be high on the agenda of all governments, foundations, and other entities that are concerned about these global issues.
