Imagine If We Stopped Animal Testing
Experimenting on animals is a dark side of science and
research. Most of us try not to think about the animals that experienced the
horrors of testing when we buy medicine or cleaning supplies. I don't know
about you, but it would make me feel a whole lot better if we could stop testing
products on animals. More than 115 million animals are used for experiments
every year. They are subjected to tests for medical, pharmaceutical, cosmetic
and even cleaning products. But animal testing doesn't always show us the whole
picture. For example, some toxicity tests on rodents are only 43% accurate at
predicting problems in humans. At least 85 HIV vaccines and some stroke drugs worked
in animal test subjects but failed in humans. So, what do you say? How about we
cancel these unreliable, animal-torturing procedures altogether? Animals make
good test subjects because they are biologically similar to us. They suffer
from many of the same health problems. And they have short life cycles. This
allows scientists to study the effects of chemicals over several generations. The
medical and pharmaceutical industries use animal test subjects to study diseases
and disorders. Animals are also used to make sure a drug, vaccine or a procedure
is safe and effective for human testing. But experimenting on animals raises
some ethical concerns. So, industries that are required to test the safety of
their products are only supposed to use animal testing as a last resort. The
pharmaceutical sector has stopped testing on animals as much. But not out of
any love for our furry friends. Newer drugs target precise molecular
mechanisms, and the best way to study them is in petri dishes. This is also
cheaper than using live animals. So, what would happen if we completely stopped
animal testing? Well, first we’d need alternatives. Luckily, we already have
some. Computers may seem like an unlikely replacement for live animals. But
they could be helpful. There are thousands of chemical compound tests in online
chemical databases. Scientists can use algorithms to get this information and compare
the tested chemical compounds with new chemical compounds. By looking at their
structural similarities, researchers can predict the toxicity of untested
chemicals. That would be a great start. But it wouldn’t be good enough to
release a new product. After using algorithms, scientists and researchers would
use other testing methods. They could move on to testing chemicals on cultured
human cells that mimic the functions of specific organs. These are called
organs-on-a-chip. And they allow researchers to test new drugs on human cells without
testing directly on humans. But I didn't say we would never do tests on humans.
OH, we would. Now, before you panic, I’m not talking about full-blown human
experimentation. That is definitely not ethical. Instead, you would volunteer to
take micro doses of a new drug. The tiny amounts wouldn’t have any huge impact
on you. But there’d be enough in your body that researchers could study how the
drug impacts your cells. But none of these great alternatives would replace
animal testing. Especially if we got ourselves into another pandemic. All the
successful COVID-19 vaccines relied on animal testing during the early research.
These tests helped scientists understand the way the immune system would
respond to the vaccine. And that is extremely important. The animal tests made
sure that the vaccines wouldn’t make the infection worse. So, if we stopped
animal testing, we’d need to advance in vitro technology. Scientists would take
some skin cells from people with a specific illness. They would make the skin
cells act more like stem cells. Then the researchers could convert those cells
into any specialized cell in the human body. So, they’d have a patient-specific
model of a disease in a lab dish. Eventually, we'd start growing actual organs
to study diseases and test experimental medicines. This would be a much more humane
way for the cosmetic, pharmaceutical, medical and household cleaning industries
to test products. And millions of animals would no longer have to suffer
experimentation for human gain. Of course, the other alternative to testing on
animals would be to stop doing science at all. But I don’t think that would
turn out very well for us. And besides, that’s a story for another WHAT IF.
