The tremendous increase in the size and growth rate of population is called population explosion. Overpopulation explosion is an undesirable situation or condition where the number of past population exceeds the carrying of universe. Over population is mainly defined as the conditionof having more people than can live on the earth in comfortably, pleasure and healthy still leave the world a suitable place for the next generations. People explosion is caused by the number of factors. Reduced mortality rate, well treatment facilities, depletion of many precious resources are few of the causes which results in overpopulation. This is possible for a sparsely populated area to become densely populated, if it is not able to sustain life.
Population explosion is a great problem now-a-days. Generally,Most of the people are careless about it . Mainly very early marriage , lack of consciousness, superstitious attitude, waiting for a mail child , ignorance and illiteracy give birth to many children . Mostly Family planning has failed. Most of the people in the name of region, custom and tradition go on increasing the number of births life saving drugs have squeezed death rate. It is generates many different type of issues in the country that main cause many problems for general people.
Population explosion mainly refers to the number of people that live in an area. Now it is a major problems for developing nations in the world . Also, the nations Government is not taking proper actions to measures to control this problems. Globally population growth amounts to around 80million+ annually. The rapidly growth of the world's population over the past hundred years results from a difference between the rate of birth and the rate of death. Mostly one of the other major problem is environmental effects of human population explosion in the world .
Infant mortality has reduced. So population is growing rapidly but It has created an explosive scenario. China has made strictly rule that - WE ARE TWO BUT WE HAVE ONE CHILD. But in India, The government has made rule WE ARE TWO AND WE HAVE TWO TOO. Many parent have dozen or half dozen of children. Every country has different rule in the world. Mostly it affects the economy of the country and It rises unemployment problem, so we should create mass awareness to check population explosion.
It occurs due to increased many health facilities and better living conditions.
1. Reasons of population explosion include
* Decreased death rate.
* Declined Maternal Mortality Rate
* Decreased Infant Mortality Rate
*Mostly Increase in the number of people in reproductive age
* Raising the marriageable age is most important.
* Couple with small families should be given some incentives
* Birth control is an important step to control the population growth by motivating smaller families by using contraceptive methods.
* In urban areas it is often found there is very less scope for making is available extra space to accommodate for additional population.
* Hence a large population is packed into a very smaller space in city area
* The population density rate.
The size of a population for any species is not a static parameter. It keeps changing with time, depending on various factors including food availability, predation, pressure and adverse weather conditions. The mass of a population in a given habitat during a given period fluctuates due to changes in basic processes.
* Nationality is the number of births during a given period in the population that are added to the initial density.
* Mostly, Mortality is the number of deaths in the population in the time of a given period.
* Is one of the most important, Immigration is the number of individuals of the same species that have come into the habitat from elsewhere during the time period under consideration.
* Most developing country have large number of people who are illiterate, so live below the poverty line and have little or no any knowledge about family planning. Getting their children married at an very quickly or early age. Many people are don't understand the harmful effects of overpopulation and lack of quality education prompts them to avoid family planning measures.
* Some of the many other causes responsible for the increase in overpopulation are joint family and lack of responsibility of many young couples in these families to bring up their children, lack of recreational facilities and wrong information about the adverse effects of vasec-tomy, tubectomy and the loop. Many poor families parents produce children not because they are ignorant but because they need them. It is evident from that fact that there are million of child workers in the world. If families stop those children from working, their family income will be terribly diminished.
* Population explosion gives rise to a number of social problems. It leads to migration of many people from rural areas to the urban areas causing the growth of jhuggi areas. People live in mostly unhealthy and insanitary conditions. Mostly unemployment and poverty lead to frustration and anger among the educated youth. This leads to robbery, beggary, prostitution and many illegal work. The moist and terrorism activist that today in various parts of the world are the reflection of frustration among educated unemployed youth.
