The Fate of Food: What We'll Eat in a Bigger, Hotter World


With crop production increasingly threatened by unpredictable weather and a world population expected to grow 30 percent by midcentury, how are we going to feed everyone? The race to reinvent the global food system is on, and solutions you’ve probably never heard of are already in play. One company is tackling problems around industrial agriculture by growing cell-based meat in a lab, eliminating both the need for animal slaughter and the grains we grow to feed them. Imagine a world where industrial animal farming and its harmful greenhouse gases no longer exist, where beef, poultry, and fish are consumed without interfering with the food chain.

How do you grow animal-less meat?

Jump to idea

Nearly 100 percent of people in the world eat meat, and 750 billion pounds of meat are consumed every year, says Uma Valeti. . So how do you ensure access to safe and healthy meat for generations to come? Valeti’s company, Memphis Meats, harvests meat from cells insteads of animals — it’s not a meat alternative or plant-based protein. The company wants to preserve people’s choice to eat meat while using fewer natural resources, producing less waste, and emitting less greenhouse gas emissions. Watch Valeti explain the process of cultivating animal cells into meat:

There’s a fundamental advantage when you grow meat from cells, says Valeti — the only job those cells have is to become high quality meat cells. They don’t have to perform natural processes like growing hair, skin, and bones, so it takes 90 percent less resources to get the same amount of meat that you would from a live animal. What’s more, the production process is much shorter; growing cell-based meat takes 3 to 4 weeks as opposed to 9, 24, or 36 months depending on the animal species. Valeti also emphasizes the safety aspect of his product — because the meat is grown in a highly controlled environment from beginning to end, contamination is less likely.

The pressures of population growth and climate change are intensifying and, at the same time, the world is seeing an increase in demand for food and a significant decrease in supply. How can we make clean, sustainable food equitable and available to everyone, not just the elite? This is a question Amanda Little, professor of investigative journalism at Vanderbilt University, found herself asking. She spent three years researching food production around the world. The answer, she says, requires synergy between diverse modes of food production.

Researchers project that every decade going forward we’ll see a 2 to 6 percent decline in food production.

In research for her book, Little explored everything from robotics, vertical farms, and GMOs to permaculture and edible insects. She says there’s a great divide between the reinventors of food and those who want food to be “de-invented.” She believes the path forward must reconcile old and new approaches to food production, and Uma Valeti agrees. “There’s a lot of tools in the toolkit we need to use,” he says. “We need conventional agriculture, regenerative agriculture, cell-based meat, we need plant-based proteins to be able to feed this growing demand.” Watch Little give an example of how modern technology can be intelligently applied to support traditional food production:

You can’t expect everyone to adopt new foods right away, says Uma Valeti, so Memphis Meats is working to demystify its cell-based products for consumers. He says personal experiences drive market growth: when you or someone you know has eaten a new product and enjoyed it. We’ve already seen that happen with products like the Impossible Burger and Beyond Meat, says Amanda Little. “There’s a lot of interest and excitement around alternatives.”

In 2018, plant-based products saw 25 percent growth in the United States, which was quadruple the growth of actual meat products.

A number of other cell-based meat startups are competing in the same space, but this doesn’t worry Valeti. Having other companies in the market is a good thing, he explains, because it proves the value of the market, gets people comfortable with eating cell-based meat, and paves the way for more innovation. As for a timeline, we can expect to start seeing products like Memphis Meats in our grocery stores within the next few years. Just like any new technology, adds Little, as time goes on it will become increasingly accessible and affordable.
