Sometimes a normal hamburger is not a normal hamburger.
A hamburger that's as healthy as
salmon certainly sounds
appetizing. This is just one of the possibilities that scientists hope to
achieve through the use of new techniques for producing cultured meat. Meat grown in a lab is an
essential technology for
expanding countries in the 21st century. _(1)_
It's not just scientists that are talking about the benefits of growing meat in
test tubes. _(2)_ If this happens, PETA would
see this development
as a major step towards reducing animal
cruelty and saving the environment. _(3)_
Cultured meat is grown by
soaking stem cells in a
nutrient-rich soup and then
manipulating them to grow into muscle
tissue. _(4)_ The meat produced so far is reported to have a
texture more like a 7-Eleven Slurpee than a
juicy steak. Also, one of the biggest problems for scientists is not how to grow the meat
in the first place. _(5)_ Real meat
is composed of a variety of textures that
tickle the
taste buds in just the right way, and this is exactly what has been giving scientists real
headaches to recreate.
(A) Instead, it's getting the taste right.
(B) With the world's
population expected to grow to nearly nine billion by 2050, scientists have suggested that
cultured meat may be
the solution to the
feared global food
shortage.
(C) The organization believes that once meat can be produced in the
lab, it will
eliminate the need for
farming and thus
cut down on greenhouse gases given off by
livestock.
(D) Animal rights organization PETA has also
offered a US$1 million prize
to any scientist who can bring cultured chicken meat to supermarkets by 2012.
(E) However, the best
ingredients for the soup and even the type of cells needed to produce the best meat remain a
puzzle for scientists.
