Scientists Can Increase People’s Lifespan To 100 Years | Band 8 IELTS Essay Sample

Sample essay

Humans are born with an expiry date. However, nowadays, people believe that scientists can make everything possible. In their opinion, scientists can make people live considerably longer lives. In my opinion, the drawbacks of living longer surpass the benefits due to the alarming socioeconomic consequences of this development.

On the one hand, increased life expectancy would help mankind in different ways. To elaborate on, if people start living longer than usual, they will be able to accomplish more and fulfil their dreams. Since professionals like scientists and technologists will be able to work for longer periods, they will also be able to discover and invent more for the world. In addition, people will have more time to spend with their near and dear ones.

On the other hand, longevity has some serious repercussions that would have detrimental impact on the world. First and foremost, unemployment and poverty rate would increase substantially, as a result of longevity. Over 8 billion people already live on earth. If the death rate reduces and birth rate remains the same, the demand for resources will increase manifold. This could even lead to wars as nations will start fighting with one another to grab the available resources.

To conclude, even though being able to live longer might seem beneficial, unless we can also increase the amount of resources available to us, this development will have grave socio-economic repercussions that will ultimately affect everyone. Hence, in my opinion, this is largely a negative development.
