People have different views about whether animal testing for medical

research

is necessary or not. From my perspective, using

animals

to

research

medicine for

humans

is terrible. The main reason why some people appreciate animal testing to conduct medical

research

is that animal testing has contributed to many cures and saved lives. Nearly every medical breakthrough in the

last

hundred years has actually resulted directly from studies using

animals

.

For example

, the experiment to remove the pancreas of a dog directly led to the discovery of insulin, which is vital to saving the lives of diabetics.

Moreover

, we can not launch a new medicine before proving it is not harmful to

humans

and laboratory mice are a suitable

research

subject because they and

humans

have biological similarities. Despite the above-mentioned advantages, in my opinion, animal testing is cruel and unacceptable. I believe that the lives of every creature are precious and

humans

have no right to torture them for our own benefit. Governments should invest in developing alternative methods that can replace the implementation of

research

on

animals

when doing medical studies.

For example

, a software program can be developed to model the human immune system and new medicines can be implemented on software

instead

of using

animals

. Hereby, there will be no more

animals

that have to endure medical tests and society can still benefit from medical development. In conclusion,

although

using

animals

in medical

research

has achieved many benefits for

humans

, it is still so cruel and should be stopped
