Overpopulation and conversations revolving around population forecast can be a very sensitive and controversial topic because they lead people to ask the same question, "What exactly is the cause, and if it does get overpopulated, what are the solutions?"

Every human being born on this earth has the right to have enough resources on earth. Still, with the population reaching about 8 billion currently, many people will be left to have a low standard of life due to the earth being pushed to its ecological breaking point. Overpopulation is a sensitive issue because it brings about a lot of questions, not only about the effects it might have on the environment but also the ethical issues it might lead to. Population Projection
Here is the growth of the world population chart that can help you clearly understand the trends. This population chart of the world contains both the global growth rate and the world population in numbers.
A few common effects of overpopulation include:
1. Ecological degradation
A population increase can put pressure on the environment, leading to decreased biodiversity, increase in deforestation, emissions, and pollutions, which will result in climate change.
2. Increased conflicts
Overpopulation leads to scarcity of resources which will cause an increase in political and social conflicts. People would be fighting for basic resources, and this turmoil would increase as the population rose.
3. Higher risk of pandemics and disasters
When wildlife habitats are destroyed for human settlement, wild animals will start having contact with humans regularly, increasing the spread of pathogens and viruses.
1. What is currently happening to the population growth rate?
The world's population growth rate in 2021 is 1.03%, which is around half the peak population rate of 1968- 2.09%. The current population in 2021 saw an increase of 1.03 % from the previous year (2020), which saw an increase of 1.05% from the population in 2019.
2. Is the population increasing or decreasing in 2020?
The population growth rate in 2020 was 1.05% which was lower than the growth rate of the previous years (1.08% in 2019 and 1.10% in 2018).
3. What is the projected population growth for 2020?
Population projections by the UN in 2017 were that there will be a decrease in the growth of the global population from 1.0% in 2020 to 0.5% in 2050 world population. These future predictions for the growth rate will gradually keep decreasing to reach 0.1% in 2100.
4. What are the 4 factors that affect future population growth?
Future growth of population is affected by four fundamental factors, and these are:
Birth rate At any particular time, if the number of births is more than the number of deaths or if the rate of death is slower when compared to the birth rate, the population will increase globally.
Death rate The mortality rate or death rate is another important factor that affects population growth. Deaths decrease the population, but with affordability and accessibility of medicines and quality health care, deaths can be lowered than the birth rates. Therefore, this increases the total population.
Immigration The movement of people into a population from other places for better job opportunities, better health care systems, social security, better education, and more is known as immigration. When people immigrate into a country, it affects the size of the population of that specific area or nation.
Emigration When individuals move out of a population due to increased war and conflict, lack of peace and social security, poor job opportunities or education systems, poor healthcare facilities, and more, the process is called emigration. The total population of that area declines gradually when people emigrate from a nation.
5. What are the 3 types of population growth?
The three types of population growth include:
6. What are the 3 factors of population growth?
The three factors that affect the growth of the population are:
7. What is the main cause of population growth?
The main cause of global population growth is the imbalance between births and deaths worldwide. This is due to the decrease in the death rate and the infant mortality rate.
8. How can we increase population growth?
Population growth can be increased exponentially if a population is given unlimited amounts of oxygen, food, moisture, and other factors that can improve the population's lifestyle.
9. What are two social factors that affect population growth?
The two important social factors that can influence the growth of the population include:
10. What are two things that increase a population?
The two things that increase the population are:
