In many countries around the world, life expectancy is increasing. Do the advantages outweigh disadvantages?

Recently, the life expectancy of citizens has been presented as a continually increasing trend in an increasing

number

of countries.

This

essay will list some merits and demerits of

this

social phenomenon, and determine whether the advantages outweigh the disadvantages. One of the compelling pros is that people living longer means that they can contribute more to the world, including human society and the natural environment.

This

is because individuals can have more time to focus on their careers or interests.

For instance

,

scientists

can discover and invent more, writers can write more valuable articles, and artists can compose more artworks;

therefore

, these results certainly benefit human society and the wild natural environment.

On the contrary

, it

also

brings a potential issue, a

population

problem. which means higher

population

pressure on earth, because the

number

of newborns increasing with the

number

of deaths will lead to a

population

explosion, and limited natural

resources

cannot satisfy human's basic needs,

such

as food, water, and housing.

Hence

, the

number

of people soaring has resulted in a scarcity of natural

resources

.

Although

increased life expectancy does bring great stress on Earth,

this

social phenomenon usually happens in most developed countries.

Furthermore

, developed countries likely have educated more

scientists

, since there are advanced educational

resources

there. So, an increasing

number

of

scientists

, especially those majoring in Environmental science, living longer and have more time to handle

this

dilemma, of a conflict between the

population

and natural

resources

. In summary, increased life expectancy may bring advantages, like individuals can have more time to contribute to

this

world.

However

, it

also

brings more pressure on natural

resources

which is the primary disadvantage. Fortunately,

scientists

may play a crucial role who are responsible for solving

this

problem to create a win-win situation. In short, in my humble opinion, its merits outweigh

demerits
