The difference between carnivores and vegetarians is clear. Carnivores
eat meat. Vegetarians do not. But would vegetarians eat meat produced in vitro - and without killing animals? Thanks
to the People for the Ethical Treatment of Animals (PETA), we may eventually
have an answer to that question.
Tastes Like Chicken
PETA is often known for its extremist views and violent actions
in support of animal rights. Recently, however, the organization was making news
by announcing a contest for producing the first in vitro meat. PETA is offering a $1 million (USD) reward to the
scientist who can produce in vitro
chicken and bring it to market by June 30, 2012. The chicken's taste and
texture must be indistinguishable from real chicken, and cannot use "animal-derived"
products other than starter cells.
Cultured Meat
The concept of in
vitro meat is not new. For years, scientists have been working to create
meat from a cell culture instead of from an animal. "Cultured meat" is created
by taking an animal's cells and infusing them with nutrients. On its website, the
non-profit organization New Harvest claims that "Cells are capable of
multiplying so many times in culture that, in theory, a single cell could be
used to produce enough meat to feed the global population for a year."
Researchers can already grow small amounts of animal tissue in
labs. Hearts, livers, bladders, and other organs have already been produced.
Some scientists now say that growing muscle tissue is the next step. Biomedical
engineer Bob Dennis from both North Carolina
State University
and the University
of North Carolina
believes that this idea is more than conceivable. "An actual whole muscle organ
is not technically impossible. But of all the tissue engineering applications
it is by far the most difficult one", says Dennis.
PETA's Civil War
This idea may seem odd to some of us carnivores, but just imagine
what the vegetarians are thinking. Ingrid Newkik, one of the founders of PETA,
said that the organization's decision to sponsor the contest has caused a "near
civil war" within its office. Despite the controversy, Newkirk says, "We don't
mind taking uncomfortable positions if it means that fewer animals suffer."
PETA's contest has shined the spotlight on such research.
One in vitro meat researcher, Henk P.
Haagsman, says that he welcomes the prize competition. While he hopes that the
field doesn't become dominated by the animal-rights issue, he hopes that the
contest will spark more interest from investors. Like other lab-meat
enthusiasts, Haagsman believes that research should focus on producing safer,
healthier meat – not only for humans, but for the environment,
too.
Mystery Meat
I'm not going to lie and say that this isn't weird to me.
I'm afraid that lab-produced meat is going to be similar to when I was told
that organic chocolate was the same as regular chocolate. It isn't! Scary isn't bad, however, so I'm keeping an
open mind. This technology has some benefits, but I'm not sure that 2012 is a
realistic deadline for putting in vitro
meat on supermarket shelves. What do you think?
