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.

There is a growing debate on animal testing which is very common in medical and other scientific research.

While

many people argue that animal experimentation should be completely banned, I agree with the opinion that

experiments

on

animals

are still necessary for

humans

and I hold the opinion that we should allow part of animal preclinical testing for critical drug research. Many people believe that animal testing should be banned for many reasons.

Firstly

, experimentation on

animals

could be cruel to them since testing

them to suffer, which is unethical, because we have no right to harm them for

humans

.

Secondly

, those

experiments

sometimes could kill

animals

, which would exasperate the environmental imbalance.

For example

of testing drugs and getting killed.

Finally

, preparations for those tests may

be harmful to

humans

, and if they are released into rivers and the ocean, they will cause serious pollution.

On the other hand

, there is another opinion arguing that we should remain animal testing. The key reason for

experiments

on

animals

is that it is necessary to use them for developing medicines. If we stop using

animals

for drug testing,

then

we

humans

need to try every kind of new drug by ourselves with a risk of getting killed, which is obviously more immoral than sacrificing

animals

. Another reason is that the suffering of

animals

can be reduced or even eliminated, which is one of the aims of researchers.

Furthermore

,

although

animal

experiments

do harm

animals

to some extent, we can minimize the harm to them by limiting the range of

experiments

.

For instance

, animal tests for the cosmetics industry are unnecessary, so we can stop using

animals

for them and leave the

animals

for more important

experiments

. In a nutshell, despite animal testing has its drawbacks, I still insist that animal

experiments

should be allowed at least in important medical research.
