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

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

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

Use synonyms

have huge benefits for human life.

First

Linking Words

, animal

experiments

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

Research

Use synonyms

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

research

using

animals

.

For example

with diabetes.

In addition

has

also

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

such

as tuberculosis, breast cancer, brain injury, or

in children.

Second

, choosing

as

subjects is better than

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

type of

Finally

Linking Words

, animal

experiments

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

humans

Use synonyms

. Evaluating the side effects of a

drug

Use synonyms

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

drug

to different organs like

humans

Use synonyms

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

animals

Use synonyms

, even the most technologically advanced products.

Therefore

Linking Words

, the sacrifice of a group of

animals

Use synonyms

is now necessary for the survival and development of mankind.

On the other hand

Linking Words

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

First

Linking Words

, from an ethical point of view, experimenting on

animals

Use synonyms

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

animals

Use synonyms

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

Use synonyms

. All living things in

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

Therefore

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

Linking Words

, products that have been successfully tested on

animals

are not sure to be absolutely safe when used for

humans

Use synonyms

. 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

before being withdrawn.

Therefore

, applying

on

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

people

Use synonyms

. In conclusion, I would concede that experimentation on

brings huge profits to

However

this

is morally wrong and

also

brings some harm to

Therefore
