1. Spread increasing awareness among people and conduct camps and education seminars for the same. 2. Increase the age limit for marriage and completely detain child marriages.
The sudden increase in population beyond the productive capacity is called as population explosion. The method of the population control are as follows; (1) Increasing the age of marriage will reduce the reproductive span and consequently the birth rate.
1 The major factors that are responsible for population explosion are illiteracy, reduced mortality, increased birth rate, and an increase in life expectancy.
- A rapid decline in death rate, maternal mortality rate, and infant mortality.
- Increase in individuals of reproductive age.
- Due to better medical facilities, the life span of people is increasing.
Some forecasters are estimating a worldwide population explosion from the current 6.6 billion people to 8 billion people by the year 2020 and to 9.4 billion by 2050. It may be that we are already too late and that the world population explosion can no longer be influenced by human agency.
Rapid population growth leads to environmental change. It has increased the number of unemployed men and women at an alarming rate. Due to this, a large number of people are being pushed into ecologically sensitive areas such as hillsides and tropical forests.
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.
- Predation. Predation refers to the catching, killing and eating of prey by its predator.
Conclusion. So we can summarise the topic by stating that population explosion is a term used to state the rapid growth of people in a particular area. It is because of lack of education, illiteracy, lack of proper knowledge of sex education, rituals, and superstition in the country's most populated area.
What does population explosion mean in AP human Geography?
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.
A population is the complete set group of individuals, whether that group comprises a nation or a group of people with a common characteristic. In statistics, a population is the pool of individuals from which a statistical sample is drawn for a study.
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.
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.
Human population growth impacts the Earth system in a variety of ways, including: Increasing the extraction of resources from the environment. These resources include fossil fuels (oil, gas, and coal), minerals, trees, water, and wildlife, especially in the oceans.
Population Explosion: Rapid increase in the population in an area consisting of human beings. The effects of population explosion include: The competition for resources. Increasing pollution in the environment. Lack of energy.
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.
Family planning awareness should be sown among the younger generations. Use of contraceptives should be encouraged. Smaller families contribute to the well being of the individual as well as to India's economy. India's vast population puts a lot of stress on the economic infrastructure.
A population is defined as a group of individuals of the same species living and interbreeding within a given area. Members of a population often rely on the same resources, are subject to similar environmental constraints, and depend on the availability of other members to persist over time.
And while every population pyramid is unique, most can be categorized into three prototypical shapes: expansive (young and growing), constrictive (elderly and shrinking), and stationary (little or no population growth). Let's take a deeper dive into the trends these three shapes reveal about a population and its needs.
