WEST SACRAMENTO, Calif. — Climate change is stressing rainforests where the highly sensitive cocoa bean grows, but chocolate lovers need not despair, say companies that are researching other ways to grow cocoa or develop cocoa substitutes.
Cocoa trees grow about 20 degrees north and south of the equator in regions with warm weather and abundant rain, including West Africa and South America. Climate change is expected to dry out the land under the additional heat. So scientists, entrepreneurs and chocolate-lovers are coming up with ways to grow cocoa and make the crop more resilient and more resistant to pests — as well as craft chocolatey-tasting cocoa alternatives to meet demand.
The push to produce cocoa indoors in the U.S. comes after other products, such as chicken meat, have already been grown in labs. It also comes as supermarket shelves fill with evolving snack options — something that developers of cocoa alternatives say shows people are ready to try what looks and tastes like a chocolate chip cookie even if the chip contains a cocoa substitute.
Yet while some are seeking to create alternative cocoa sources and substitutes, others are trying to bolster the supply of cocoa where it naturally grows. Mars, which makes M&Ms and Snickers, has a research facility at University of California, Davis aimed at making cocoa plants more resilient, said Joanna Hwu, the company's senior director of cocoa plant science.
