Population explosion is condition where an organisms numbers exceeds carrying capacity of its habitat.It is a curse and is damaging to the development of the country and its society.The developing countries already facing lack in their resourses,and with the rapidly increasing population,the resourses available per person ,further leading to increased poverty,malnutrition and other large population related problems.
The literal meaning of population is “the whole number of people or inhabitants in a country or region” and the literal meaning of population explosion is “ a pyramiding of numbers of a biological population”.
As the number of people in pyramid increases,so do the problems related to population explosion also increases.
FACTORS AFFECTING POPULATION CHANGE:
The main factors affecting population change are the birth rate,death rate and migration.
The birth rate is ratio between the number of births and individuals in specified population and time.
The death rate is ratio between the number of deaths and individuals in specified population and time.
The migration is the number of people moving in(immigration) and number of people moving out(emmigration) of country,place or locality.
The population change is calculated by the formula
Population change =(Births + Immigration)-(Deaths + Emmigration)
The recent increase in the world population has been caused due to the following major reasons:
1. The increase in birth rates due to medical improvements.
2. The decrease in death rates due to better medical facilities and advancements in the field of medicine.
3. Immigration to better developed countries due to several reasons like better job opportunities, war, and natural causes like hurricanes, earthquakes, and so forth.
India, being a developing country, has had to face several economic and political challenges. One of the most important problems is the population explosion. Some of the reasons for this population explosion are poverty, better medical facilities, and immigration from the neighboring countries of Bangladesh and Nepal. Several solutions to decrease the rate of population increase have been tried by the government, some successful, some unsuccessful. Although the rate of increase has decreased, the rate has not reached the satisfactory level yet.The population in India continues to increase at an alarming rate. The effects of this population increase are evident in the increasing poverty, unemployment, air and water pollution, and shortage of food, health resources and educational resources.
REASONS FOR INCREASE IN POPULATION:
1. BIRTH RATE:
According to recent news, India currently faces approximately “33 births a minute, 2,000 an hour, 48,000 a day, which calculates to nearly 12 million a year”. Unfortunately, the resources do not increase as the population increases. Instead the resources keep decreasing, leading to making survival for a human being more and more competitive even for the basic necessities of life like food, clothing and shelter.
India currently faces a vicious cycle of population explosion and poverty. One of the most important reasons for this population increase in India is poverty. According to Geography.com, “More than 300 million Indians earn less than US $1 everyday and about 130 million people are jobless.” The people, who have to struggle to make two ends meet produce more children because more children mean more earning hands.Also, due to poverty, the infant mortality rate among such families is higher due to the lack of facilities like food and medical resources. Thus, they produce more children assuming that not all of them would be able to survive. The end result is a mounting increase in the population size of India. Due to the increase in...
