Nowadays animal experiments are widely used to develop new medicines and to test the safety of other products. Some people argue that these experiments should be banned because it is morally wrong to cause animals to suffer, while others are in favour of them because of their benefits to humanity. Discuss both views and give your own opinion.

In the modern era, there has been a great deal of discussion revolving around the issue of animal testing. Some

people

assert that these

experiments

ought to be disallowed because they involve moral issues, whereas many others argue that they strongly believe it brings a huge value to our lives.

This

essay will discuss both sides of

this

argument and present my personal view in the conclusion. On the one hand, it is understandable why many

people

believe that medicines tested on

animals

have huge benefits for human life.

First

, animal

experiments

have contributed to the development of many treatments and saving human lives. The California Biomedical

Research

Association has stated that nearly every medical breakthrough in the past 100 years has resulted directly from

research

using

animals

.

For example

, an experiment to remove the pancreas in dogs helped detect insulin - the key factor in saving the lives of

people

with diabetes.

In addition

, animal

research

has

also

contributed to great advances in deeply understanding and treating many serious diseases

such

as tuberculosis, breast cancer, brain injury, or

leukemia

in children.

Second

, choosing

animals

as

research

subjects is better than

humans

because their life cycles are shorter.

For example

, mice in the lab only live two to three years, so researchers can study the impact of treatments or genetic problems over their lifetime or over generations.

This

is impossible on a human subject. Especially for long-term cancer

research

, because of its short lifespan, rats are particularly well-suited to

this

type of

research

.

Finally

, animal

experiments

help test the safety of medicinal products before they are used in

humans

. Evaluating the side effects of a

drug

requires a genome close to that of a human and a circulatory system to carry the

drug

to different organs like

humans

. And so far there is no suitable substitute for testing a medicinal product in living organisms rather than

animals

, even the most technologically advanced products.

Therefore

, the sacrifice of a group of

animals

is now necessary for the survival and development of mankind.

On the other hand

, there are many reasons why animal experimentation should be banned.

First

, from an ethical point of view, experimenting on

animals

is seen as cruel and inhumane. In fact, most of the

animals

used in the

experiments

were forced to eat, or live in conditions of lack of food and water, and were harmed for the purpose of medical

research

. All living things in

this

world, whether

humans

or other

animals

, have equal rights, and they all have their own roles in balancing the ecosystem.

Therefore

, they all have the right to live

and to be respected.

Animals

, like

humans

,

also

have feelings of pain or fear, desire to exist, and have no obligation to make sacrifices to satisfy human interests.

Second

, products that have been successfully tested on

animals

are not sure to be absolutely safe when used for

humans

. A prime example in history is the sleeping pill thalidomide which caused 10,000 severe birth defects in babies in the 1950s, even though it was tested in high doses on a variety of

animals

before being widely released.

Similarly

, animal testing of the arthritis

drug

Vioxx showed a cardioprotective effect in mice, but the

drug

, in fact, caused multiple heart attacks and sudden cardiac death in

humans

before being withdrawn.

Therefore

, applying

experiments

on

animals

and being over-confident in its results can lead to wrong decisions and endanger

people

. In conclusion, I would concede that experimentation on

animals

brings huge profits to

humans

.

However

,

this

is morally wrong and

also

brings some harm to

people

.

Therefore

, I think it is better for us to limit

drug

testing on

animals

.
