▶ Your Answer :
Undoubtedly, human life span has been longer
and longer as time passes by. Some people might say that the main reason is development
of education systems or improvement to our diets. There are numerous factors
that contribute to this phenomenon. If were asked to choose the most important
cause of the expansion of human’s life span, I would say that technological improvement
is the most crucial reason for this. There are some reasons and examples as follow.
To
begin with, a development in medical technology made people to live longer
lives. Long time ago, lots of diseases led people to death. For example, in the
Middle Ages, there was an epidemic disease that swept Europe which is known as
the Black Death. However, due to the improvement of medical technology, most
diseases that were not able to be cured are now can be cured. Some diseases
that were prevailed in the past like a chicken pox have almost disappeared. This
liberation from diseases helped the life span of human to increase over an
average age one-hundred.
In addition,
a development in environmental technology contributed to longer life span of human.
Due to the utilization of environments, they are severely destroyed nowadays. A
destruction of environments sometimes has negative effects to human through
direct methods like water and air. For example, drinking polluted water and
breathing polluted air might cause diseases which make people die earlier.
However, lots of technologies to purify environmental pollution have invented.
Therefore, people can maintain their lives in better living conditions which make
their life span much longer than before.
As I
mentioned above, modern technologies have played an important role in lengthening
people’s life span. All in all, I strongly believe that the improvements of
technology will continue to affect people’s lives positively in the future.
