    Recently I rolled into a local restaurant to try an Impossible Burger, an all-plant patty(人造肉饼) invented by Impossible Foods. It's well known for having an strangely chewy(有咀嚼感), even bloody, meat-like quality, a surprising verisimilitude(逼真) that has made it ''perhaps the country's most famous burger, '' as New York magazine wrote. One bite into its wonderful, smoky taste and, damn, I was convinced.

    This is good news, because the time has come to consume fake meat. In the fight against climate change, meat replacement is something we can try. A University of Oxford study recently found that, to keep global warming below 2 degrees this century, we need to be eating 75 percent less beef and 90 percent less pork.

    However, diets are culturally enshrined, so changing them will be hard. It isn't easy to replace 75 to 90 percent of beef and pork with fake meat. The first taste of an Impossible Burger—a moment when low expectations work a powerful magic in the product's favor—is one thing. But how do you keep meat-eaters asking for more after their sixth, and their 26th？

    To get to true mass adoption, fake meat will need to compete favorably with the real thing on multiple fronts. Impossible Foods' goal is to drive the price of its product below that of Safeway's 80/20 hamburger meat, at which point people will simply vote with their wallets. The new industry also wants to improve on animal flesh in various ways. Fake meat has an advantage over traditional meat because ''you won't need to refrigerate it'' cofounder Niko Koffeman says. Plus, custom(定制的) production could improve choice. ''You could have very soft and tender meat for elderly people,'' Koffeman adds. ''You could have a tailored meat for whatever you need.''

    You can tell the world is shifting this way, because the ranchers(牧场主) are nervous. Last year, the US Cattlemen's Association asked the government to define ''meat'' as a product ''coming directly from animals.'' That anxiety—and the power of the science driving it—goes to show that this grand shift isn't impossible.
