You've heard of lab-grown gemstones. But how would you feel
about lab-grown meat? A group of scientists from Eindhoven
University in the Netherlands have succeeded in culturing pork
in a petri dish. Researchers extracted cells from the muscle of
a live pig, then incubated them in a nutrient-rich solution,
creating a sticky tissue that's being described as a "soggy form
of pork."  There are still challenges to overcome — like how to
achieve a firm consistency — but scientists believe an in-vitro
meat breakthrough will happen and processed meat products could
be manufactured from lab meat in as little as five years.
Cultured meat has the potential to reduce billions of tons of
greenhouse gases emitted every year by farm animals. PETA even
acknowledged, "If meat is no longer a piece of a dead animal,
there's no ethical objection." But I disagree. In addition to
blurring the lines between natural and artificial, something
like cultured pork would complicate the ethics of eating meat,
complicate vegetarianism, an
