article on a increase population
Answers
There are currently 7.7 billion people on our planet. India itself has a population of 1.3 billion people. And the population of the world is rising steadily year on year. This increase in the population, i.e. the number of people inhabiting our planet is what we call population growth. In this essay on population growth, we will see the reasons and the effects of this phenomenon on our planet and our societies.
One important feature of population growth is that over the last century it has shown exponential growth. When the pattern of increase is by a fixed quantity, we call this linear growth, for example, 3, 5, 7, 9 and so on. Exponential growth shows an increase by a fixed percentage, for example, 2, 4, 8, 16, 32 and so on. This exponential growth is the reason our population has seen such an immense increase over the past century and a half.
Causes of Population Growth
To fully understand the phenomenon, in this essay on population growth we will discuss some of its causes. Understanding the reasons for such exponential growth will help us better understand how to plan for the future. So let us begin with one of the main causes, which is the decline in the mortality rate.
Over the last century, we have made some very significant and notable advancements in medicine, science, and technology. We have invented vaccines, found new treatments and even almost completely eradicated some life-threatening diseases. This means that people now have a much higher life expectancy than their ancestors.
Along with the decrease in mortality rate, these advancements in medicine and science have also boosted the birth rates. We now have ways to help those with infertility and reproductive problems. Hence, birth rates around the world have also seen massive improvements. This coupled with slowing mortality rates has caused overpopulation.

Answer:
The rapid growth of population is one of the greatest obstacles in the progress of developing countries. If the population grows fast, poverty cannot be eradicated. Progress made in the fields of agriculture, industry and technology fails to cope with the needs of a rapidly growing population.Thus, overpopulation leads to poverty and unemployment.
A high rate of birth and a decline in death rates have resulted in population explosions, especially in underdeveloped countries. The Census Report of 2001 states that while in Europe, the population growth rate is 0.3 per cent, in India it is about 2.1 per cent. Countries like Scandinavia and Russia have a negative growth of population which also leads to problems like shortage of manpower.If the world population can be evenly distributed and a free flow of people throughout the world ensured, the problem of population explosion may be solved. Besides, to counter excessive population, the government should take up family planning schemes and spread awareness and literacy. The Indian government has taken up several family planning projects.
