What do you mean by population explosion answer?
It is a sudden increase in number of individuals in a specific area at a given time. Population explosion is a cause of serious concern for all of us . Its impact is already showing in many areas caused by a sudden increase in population. The world population is growing at the rate of 2% per year.
The rapid growth of the world's population over the past one hundred years results from a difference between the rate of birth and the rate of death. The human popula-tion will increase by 1 billion people in the next decade. This is like adding the whole population of China to the world's population.
It can lead to competition for essential requirements like food, shelter clothing, etc. It can lead to the depletion of natural resources. It can increase the pollution of the environment due to increased automobile usage. It can lead to unemployment and unhygienic living conditions.
1 The major factors that are responsible for population explosion are illiteracy, reduced mortality, increased birth rate, and an increase in life expectancy.
More than half of global population growth between now and 2050 is expected to occur in Africa. Africa has the highest rate of population growth among major areas. The population of sub-Saharan Africa is projected to double by 2050.
Population explosion: A crisis in which population growth occurs in countries ill- prepared to handle the growing numbers of people. Ecumene: The term for habitable land, which includes land with adequate water sources, relatively flat terrain, and available human food sources.
More people means an increased demand for food, water, housing, energy, healthcare, transportation, and more. And all that consumption contributes to ecological degradation, increased conflicts, and a higher risk of large-scale disasters like pandemics.
The population explosion first occurred on a small scale and with a relatively moderate intensity in Europe and America, more or less between 1750 and 1950. From 1950 on, a much more substantial and intensive population explosion started to take place in Asia, Latin America and Africa (Fig. 2).
The main reason for the population explosion is the rapid fall in the mortality rate, creating an imbalance between birth and death. The mortality rate is decreasing rapidly due to advanced medical facilities and development in healthcare. Moreover, due to these advancements total fertility rate has also increased.
One of the largest environmental effects of human population growth is the problem of global warming. Some scientists fear that global warming will lead to rising sea levels and extreme weather conditions in the future. In order to support the growing population, forests are being destroyed at an alarming rate.
How is population explosion controlled answer?
Marriageable Age. Raising of the age of marriage is more effective means to control the population (now marriageable age of female is 18 years and that of male is 21 years).
A consequence of the decline in mortality in Stage Two is an increasingly rapid growth in population growth (a.k.a. "population explosion") as the gap between deaths and births grows wider and wider. Note that this growth is not due to an increase in fertility (or birth rates) but to a decline in deaths.
Population growth is the increase in the number of people in a population or dispersed group. Actual global human population growth amounts to around 83 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7.9 billion in 2020.
Overpopulation adversely impacts the economy. Rising prices cause less savings and make the working and middle classes more vulnerable to economic distress. In developing countries, people are forced to go without clean water or adequate food and live in squalid conditions.
