Overpopulation is one of the major problems facing the planet today, as it directly or indirectly fuels issues like pollution and global warming. The global population has grown continuously since 1400 AD but most significantly over the last 50 years due to medical and agricultural advances. Overpopulation is caused by declining death rates, rising birth rates, migration, and lack of education. Potential solutions include continuing efforts to reduce suffering from disease and poverty, improving resource efficiency and pollution control, and keeping population numbers sustainable.
Overpopulation is an undesirable condition where the number of existing human population exceeds the carrying capacity of Earth. Overpopulation is caused by number of factors. Reduced mortality rate, better medical facilities, depletion of precious resources are few of the causes which results in overpopulation.

Population : The word population has been derived from the Latin word “populatio” which means people.
The group of individual species which occupy a definite geographic area is defined as population.
Population Growth : The change in population per unit area at particular time is called population Growth.
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 rapid increase in population over a relatively short period is called population explosion.
“Development is the best contraceptive,” made by Dr Karan Singh at the World Population Conference in Bucharest in 1974, highlighted a change of thinking and the need for a more balanced approach to population control.

INTRODUCTION
Historical shift from high birth rates and high death rates in Societies with minimal technology, Education ( women) and economic development TO Low birth rates and low death rates in societies with advanced technology, Education and Economic development And the stages between these two scenarios.
Scholars debate
whether industrialization and higher Income lead to lower population,
OR
whether lower populations lead to industrialization and higher Incomes ?
Definition
WARREN C. Thompson, Frank w Notestein.
A historical process of change which accounts the trends in births, death and population growth occurred in today's industrialized societies, especially European societies.
Definition by Dolan
“Demographic transition refers to a population cycle that begins with a fall in death rate, continues with a phase of Rapid population growth and concludes with a decline in birth rate”
DEMOGRAPHIC STAGES
STAGE ONE
Pre- Industrial society, death rates and birth rates were both high
These rates fluctuated rapidly according to natural events such as
Drought
Diseases
to produce a relatively constant and young population.
Family planning and contraception were virtually non-existent.
Death rates matched birth rates exceeding 40 per 1000 per year
Children contributed to the economy of the household from an early age by carrying water, firewood and messages, carrying for younger siblings, sweeping washing dishes, preparing food and working infields.
There was no much education or entertainment expenses.
Thus the total cost of raising children barely exceeded the contribution to the household.
During this stage, the society evolve in accordance with Malthusian paradigm - with Population essentially determined by the food supply.
Eg: - Any fluctuations in food supply tend to translate directly into population fluctuations
EG: - Famines - Resulting In significant mortality which are frequent.
According to Edward, Revocatus ( 2016) - This is the earlier stage of demographic transition in the world
which is characterized by primary activities such as small fishing activities, farming pastoralizing and petty businesses.

In this chapter, you will learn about how the human population change over the centuries and why those changes occur. You will also discuss the arguments regarding population and resources - the ideas of Thomas Malthus and Ester Boserup.
Population growth is the change in a population over time, and can be quantified as the change in the number of individuals of any species in a population using "per unit time" for measurement.
Over population is defined in human context as the state where the number of existing human population exceeds the carrying capacity of the earth.
The Food and Agriculture Organization (FAO) is specialized agency of the United Nations that leads international efforts to defeat hunger.
Their goal is to achieve food security for all and make sure that people have regular access to enough high-quality food to lead active, healthy lives. With over 194 member states, FAO works in over 130 countries worldwide. They believe that everyone can play a part in ending hunger.

In a May 9, 2024 paper, Juri Opitz from the University of Zurich, along with Shira Wein and Nathan Schneider form Georgetown University, discussed the importance of linguistic expertise in natural language processing (NLP) in an era dominated by large language models (LLMs).
The authors explained that while machine translation (MT) previously relied heavily on linguists, the landscape has shifted. “Linguistics is no longer front and center in the way we build NLP systems,” they said. With the emergence of LLMs, which can generate fluent text without the need for specialized modules to handle grammar or semantic coherence, the need for linguistic expertise in NLP is being questioned.

2. • Overpopulation is one of the major problems
the planet is facing today, and it directly or
indirectly fuels other problems, ranging from
pollution to global warming.
• The population has been growing
continuously since the end of the Black
Death, around the year 1400,although the
most significant increase has been in the last
50 years, mainly due to medical
advancements and increases in agricultural
productivity
3. Reason of over population:
• Decline in the Death Rate
• Rise in the Birth Rate
• Migration
• Lack of Education
4. solutions:
• continue to strive to reduce suffering by
combating disease and poverty around the
world
• continue to improve resource efficiency and
pollution control so that standards of living
can rise without negative impact; and
• keep human population to numbers that are
sustainable.
