World population exceeds 8 billion: is it to celebrate or hold your head?

World population exceeds 8 billion: is it to celebrate or hold your head?

The world population today reaches 8 billion people, a population four times larger than the world had in 1927. The 2022 revision of the United Nations population estimates that this population will reach 9 billion in 15 years. The population increase will be concentrated mainly among the lowest-income countries.

The increase in world population in the last hundred years is the result of two important trends. The increases in life expectancy at birth are due to improvements in public health, personal hygiene and medicine in some countries of the world. 

The symbolic day will be this Tuesday the 15th. The UN itself speaks of overpopulation and vast sectors with insufficient resources. Unprecedented social and environmental challenges. The unequal economic relations.

Despite the fact that all the countries have begun the demographic transition, with the decrease in mortality and fertility. In some countries, there are still high global fertility and adolescent fertility rates. The timing and pace of fertility decline across countries and regions. Coupled with continuing reductions in mortality have meant that births continue to outnumber deaths globally, and thus the world population continues to grow.

It has been told in this report that the average age of humans has also been 72.8 years. It has increased by nine years till 2019 as compared to 1990. And by the year 2050, the average age of men will be 77.2 years. On the other hand, women live an average of 5.4 years more than men. Their average age has been estimated at 73.4 years and that of men at 68.4 years.

Population growing at slowest rate since 1950

According to the United Nations report, it is a milestone in human development. Improvement in public health, nutrition, sanitation and medicine is considered an important reason behind this growth.

It has taken 12 years for the global population to grow from 7 to 8 billion, and it will reach 9 billion by 2037. Along with this, the overall growth rate of the global population is slowing down.

However, fertility has declined in many countries. The population is growing at the slowest rate since the 1950s. In the year 2020, it has reduced to less than one per cent.

With this, India will become the most populous country by the year 2023 leaving behind China. The world population is estimated to reach 1040 crores around 2080.

India, Pakistan, Congo, Egypt, Ethiopia, Nigeria, Philippines and Tanzania will have 50 per cent of the world’s population by 2050.

According to the report of the Institute of Health Metrics Evaluation, after 78 years, the TFR in India will be at 1.29. Which is far less than the UN’s estimate of 1.69. India’s population may be reduced by 433 million from the estimated estimate in the year 2100.

Between 2010 and 2021, 1.65 crore Pakistanis left their country and immigrated to other countries. After this 35 lakh, people migrated from India, 29 lakh from Bangladesh, 16 lakh from Nepal and 10 lakh from Sri Lanka.

Population rise is distributed

The UN announcement does not change reality. That the world harbours those it harbours, whether there are many or enough of them, does not matter from last week to the next. As long as economic and population relations do not change. As long as the population rise is distributed among voracious megacities that consume resources. And excrete waste and a rural environment that produces food and is impoverished.

It does serve to know that the growth rate has come to a standstill and that with sustained ageing the hope of rejuvenation is placed in Africa, the only continent that does not have a stagnant birth rate but where poverty and hunger are devastating. For the moment, in the immediate future, the most important thing is that next year India will have surpassed China in terms of the number of inhabitants.

The question today does not happen if we are too many. But because we require many more biological resources (forests, fish, land). Then the planet can generate, we have excessive consumption of fossil fuels. Which produces carbon dioxide emissions. of carbon that causes global warming, the room of academics at American Rockefeller University reacted to the news.

According to the World Wide Fund for Nature, it would take 1.75 planets to support the world’s population.

Challenges 

The challenges are many since the COVID-19 pandemic and the displacement of people from conflict zones have generated a deterioration of the parameters that allow increasing life expectancy. Thus, a UN report pointed out that SARS-CoV-2 reversed decades of progress in terms of poverty, health and education.

Natalia Kanem, executive director of the United Nations Population Fund (UNFPA), said that reaching 8,000 million inhabitants “is a momentous milestone for humanity” and assured that “some express their concern that our world is overpopulated with too many insufficient people and resources to sustain their lives. I am here to say clearly that the sheer number of human lives is nothing to fear.”

According to demographic data, half of the population still lives in just 7 countries: China, India, the United States, Indonesia, Pakistan, Nigeria and Brazil. India’s population could surpass that of China in the coming years.

Points

  • Extreme poverty has decreased and income inequality between countries has been reduced considerably in the last 25 years, according to UN data.
  • The proportion of people living in extreme poverty, that is, on less than $2 a day, has fallen from 44% in 1974 to 10%, according to data from GapMinder.
  • At the same time, there are challenges facing large parts of the world.
  • Climate change continues to pose one of the greatest threats to humanity, according to the UN. Developments in low-income parts of the world could complicate global efforts to reduce its impact.
  • A record 100 million people have been forcibly displaced from their homes. This was made worse by the Taliban’s takeover of Afghanistan and Russia’s invasion of Ukraine.
  • Famines do not stop despite the progress made. Thus, in the region known as the Horn of Africa, international aid agencies continue to work to mitigate the effects of conflicts and crises.
