Overpopulation has becomes a terrible
problem in the world. All of the countries are suffering from this problem
directly or indirectly. China, India, Nepal and other countries are suffering
from this problem. There is regularly change between birth rate and death rate.
Birth rate was slightly higher than the death rate. Therefore, world population
grew at a very slow rate. A few hundred years ago, however, the situation began
to change, especially in the industrialized countries. With advances in
nutrition, sanitation, and health, people live longer. For the first time, the
balance between birth rate and death rate has been badly disturbed. During the
last three centuries, the world population has been rapidly going up.
Rapid growth of population can be
realized in Nepal, too. In 1951, Nepal’s population was 9 million. Less than
half a century later that number rose to 23 million. We can easily assume the
future of Nepal with this annual growth rate of 2.5%. If this is not checked,
Nepal’s population will double in just 28 years. By the year 2026, there will
be a total of some 46 million.
There is not any advantage of growth of
population. Rather there are many disadvantages. Deforestation is result of the
overpopulation. Most of the forests have been destroyed for expansion of land
for cultivation and also for building home. Deforestation upsets the natural
rain. We have comparatively less rain. Besides, there are landslides. Wild
animals disappear which are also part of eco-system. Naturally, we are
affected. We have less food. Our environmental conditions decline.
Moreover, because of the overpopulation
we continue to litter our surroundings. High temperatures, floods, tropical
diseases and mass migrations are all results of overpopulation. The country
cannot invest money on development fields. Therefore, poverty, unemployment,
illiteracy, etc. all rise higher and higher. Therefore, it is necessary to stop
and control the increasing rate of population.
