In modern world, it is no longer necessary to use animals for food or use animal products, for instance, clothing and medicines. To what extent do you agree or disagree.

Nowadays, it is widely acknowledged that many products made from

animals

like

food

or

clothes

can be replaced by other modern versions. Based on that trend, even though some

people

say we no longer need to depend on

animals

to satisfy our lives, I would argue that we still need animal products to some extent, especially in doing research about

medicine

. For

clothes

,

animals

used to be the major sources of materials to produce our outfits. Hundreds of thousands of

years

ago, humans knew how to use the skins of big

animals

like bears or tigers to cover their bodies to survive during winters. Even in modern times, during the twentieth century, rich

people

and celebrities in many western countries still held the belief of the necessity of using

animals

that way for making our outfits. Only for the

last

few decades,

this

has been strongly opposed by many environmentalists, activists, wildlife conservationists, and

then

politicians and governments because of the immorality of sacrificing

animals

just to make what

people

wear and the growing support for the necessity of nature conservation.

Moreover

, thanks to the development of science and technology, authentic materials have been discovered and industrially made for the specific purposes of making

clothes

with many advantages like various colours, cheaper prices and especially no requiring killing

animals

.

Therefore

, we now and never will need

animals

to satisfy our wearing demands. In the case of

food

,

animals

are still the sources of what we eat to some extent. Livestock has provided meat for humans since the agricultural revolutions thousands of

years

ago, and nowadays are still doing that work in most countries around the world.

People

have depended on meat and fish for a very long time;

hence

it would be difficult to change

people

's behaviours, and the husbandry will remain significant in our modern economy. Until very recently, artificial meats have been invented with the specific benefit of not depending on raising

animals

, and

therefore

are believed to be very promising to replace beef and fork in the coming

years

.

However

, more tests and trials need to be done to guarantee whether the general public would accept that new types of meats since they still can feel the slight difference between the animal-based version and the lab-growing one in terms of taste. In short, the dependence on

food

from

animals

is still significant but there is clear evidence to say that it will not

last

for long. Turning to

medicine

,

animals

are crucial more than ever. In the

last

100

years

, more diseases have been discovered, along with more

medicine

has been created to save human lives. Even now, pharmaceutical research and experiments are being conducted worldwide to fight against cancers, cardiovascular diseases and many others. To satisfy the demands of saving patients, drugs need to be tested before being produced at industrial scales and scientists are still using

animals

like mice to check the effectiveness of the new

medicine

in the real organisms.

That is

, unfortunately, still the only visible way to make sure the safety of the drug and there is still no other option equally feasible.

As a result

, modern humans still need

animals

to make

medicine

to protect themselves. In conclusion,

although

we have been successful at stopping killing

animals

for

clothes

, there is still a long way to do the same thing in the case of

food

, and I still do not see any scenario in which

medicine

could be developed without using

animals

in foreseeable future.
