The term human overpopulation refers to the relationship between the entire human population and its environment: the earth, or to smaller geographical areas such as countries overpopulation can result from an increase in births, a decline in mortality rates, an increase in immigration, or an unsustainable biome and depletion of resources. In biology or human geography, population growth is the increase in the number of individuals in a population global human population growth amounts to around 83 million annually, or 11% per year the global population has grown from 1 billion in 1800 to 7616 billion in 2018.
Overpopulation can further be viewed, in a long term perspective, as existing if a population cannot be maintained given the rapid depletion of non-renewable resources or given the degradation of the capacity of the environment to give support to the population changes in lifestyle could reverse overpopulated status without a large population reduction. The effects of population explosion in india are as follows: over-population: population explosion may lead to overpopulation, ie, a condition where population surges to a level that the earth cannot accommodate comfortably, and poses a threat to the environment.
Population explosion definition, the rapid increase in numbers of a particular species, especially in the world's human population since the end of world war ii, attributed to an accelerating birthrate, a decrease in infant mortality, and an increase in life expectancy see more. Population explosion defined as a significant number of people staying in the individual area it is a huge problem in india in fact, in all over the world, it is increasing, especially in the poorer countries it is developing. A fast increase in the creation of a species is called a population explosion an example of a population explosion occurred when world war ii ended, and the human population increased dramatically due to an accelerated birth rate, a rise in life expectancy and a decline in infant deaths the.
The population explosion was “the most important, astounding, and far-reaching event of the twentieth century,” say the ehrlichs it threatens the very habitability of the planet why has there been so little discussion of it. It may sound queer, but the law is that the poorer a country the greater is the growth rate of its population india, caught in the morass of her age-old poverty, finds herself in the midst of a population explosion the population that was less than 400 million in the forties was found to be about 121 billion in 2011 census.
Population explosion n the geometric expansion of a biological population, especially the unchecked growth in human population resulting from a decrease in infant mortality and an increase in longevity population explosion n (sociology) a rapid increase in the size of a population caused by such factors as a sudden decline in infant mortality or an.
This combination of high birth rates and low death rates have led to the population explosion in many countries throughout the world the end of the population explosion worldwide will be determined by how much countries invest in family planning efforts to lower fertility and slow down popula-tion growth. Population explosion refers the sudden and rapid rise in the size of population, especially human population it is an unchecked growth of human population caused as a result of: increased birth rate, decreased infant mortality rate, and improved life expectancy a drastic growth in population beyond normal limits is called population explosion. Although this unit is intended primarily for students in grades 5-8, teachers in both elementary and high school can use this unit to explore key ideas and concepts about the population explosion.
