The Company Leading the Future of Farming
Here's a crazy idea: Combine bioprinting
and tissue engineering to "print" animal products and tackle some of
the planet's biggest problems. Animal farming, after all, accounts for about
half of all human-caused greenhouse gases, taking place on one-third of the
available, non-frozen land on Earth. All to feed people's appetites for 300
million tons of meat a year.
Modern Meadow is a Missouri-based startup
that engineers tissues to create lab-grown edible meat, in a process that
eliminates many of the negative environment effects associated with traditional
livestock practices.
The company claims that by carefully
layering mixtures of cells of different types in a specific structure, in-vitro
meat production becomes feasible. It’s set a short-term goal of printing a
sliver of meat around two centimeters by one centimeter, and less than half a
millimeter thick, which is edible.
The company explains in a submission to the
United States Department of Agriculture: “The technology has several advantages
in comparison to earlier attempts to engineer meat in vitro. The bio-ink
particles can be reproducibly prepared with mixtures of cells of different
type. Printing ensures consistent shape, while post-printing structure
formation and maturation in the bioreactor facilitates conditioning.”
However, it admits that the road ahead is
strewn with difficulties. “The consumer acceptance of such products may not be
without challenges. We expect it will first appeal to culinary early-adopter
consumers and the segment of the vegetarian community that rejects meat for
ethical reasons. With reduction in price, it can reach the masses with religious
restrictions on meat consumption (people restricted to Hindu, Kosher, Halal
diets) and finally populations with limited access to safe meat production.”
Whatever the final outcome, lab-grown
edible meat is no longer in the realm of science fiction. It is coming.
1. Animal farming is responsible for the
occurrence of greenhouse gases.回答
2. Modern Meadow is a newly-started
business which aims to make profits by producing lab-grown edible meat.回答
3. The method Modern Meadow adopted to
produce in-virto meat is by layering mixtures of cells of different types in a
specific structure.回答
4. There is no meat engineered outside
living bodies before.回答
5. This lab-grown meat has already widely
received by the masses.回答
