According to forecasts of the United Nations on November 15, the population of people on Earth passed eight billion. The forecast attributes this rise to longer life spans due to improved access to medical care, better nutrition, improved personal hygiene and advances in medicine.
While population growth stagnates or declines in some countries, high birth rates persist in other countries, and this is another important factor for global population growth.
We often don’t even realize the amount of people on Earth and how this mass is changing the world. if we collected all the biomass of mammals – from mice, through bats and antelopes to whales – so 64% of it would be farm animals – i.e. cattle, pigs, sheep, goats, buffaloes. 32% would be made up of humans (because we too belong to mammals – Mammalia). And only 4% would be left for those mice, bats, antelopes and whales, i.e. all wild mammals.
“Eight billion people. This is an important milestone for humanity,” says the Executive Director of the UN Population Fund, Natalia Kanemová. “However, I realize that this moment may not be greeted with joy by everyone. Some people express concern that our world is overpopulated. I am here to make it clear that the mere number of human lives is not a reason for fear.” Kanemová thus warns against “population alarmism”.
There is no denying that the increase in world population is increasing the pressure on the Earth’s resources. However, many experts consider excessive consumption in rich countries to be a bigger problem. There’s definitely something to it. If everyone in the world lived the way Americans live, it wouldn’t be enough to meet their demand not even five planets like Earth. If everyone lived at the same level as the people of India, then the burden on the globe is one-seventh of the current state.
“The impact on the planet depends much more on our behavior than on our numbers,” says Jennifer Sciubbová of Wilson Center. “Emphasizing the total number of people makes it easier for people in richer countries to shift the blame to developing countries where population growth is highest.”
Population growth cannot be ignored
But a number of experts are inclined to the opinion that the global increase in population cannot be ignored. The world’s population is growing at a rate that exceeds 70 million per year, with 80% falling on the poorest countries, which have the least capacity for sustenance, education and employment of these people. Population growth there contributes to poverty and environmental devastation. If this increase could be slowed down, the economic and environmental benefits would be truly significant.
He lives in the world as a whole 700 million people in extreme povertywith the highest concentration of extreme poverty he is in africa. 23 of the 28 poorest countries in the world are located on this continent. It is not by chance that Africa has highest birth rate and fastest population growth in the world.
In addition, they also suffer from climate instability, lack of water or floods. Many people do not have enough food. Inflation and rising fuel costs make life even more difficult for them. Some analysis prove that the situation in sub-Saharan Africa will become unsustainable before 2050. These analyzes point to rapid population growth as one of the main risk factors.
According to a UN report published earlier this year, nearly half of all pregnancies on our planet are unwanted. The path to a lower birth rate leads through education, family planning and the use of contraception. However, people in poor countries with rapidly growing populations do not have sufficient access to these means to limit population growth.
Outlook to the year 2100
Back in 1950, the global population was only 2.5 billion people. Since then, the population of our planet has increased by more than 300%. According to the UN, however human population growth is slowing down. The population of the Earth grew from seven to eight billion in twelve years. Another billion will be added in fifteen years. In most countries of the world, there are no longer enough children being born to naturally restore the population and maintain it at a stable level.
Yet the Earth’s population will increase to 8.5 billion by 2030, to 9.7 billion by 2050, and to 10.4 billion by 2100. This increase will be concentrated in a relatively small number of countries. More than half of the projected population growth by 2050 will occur in just eight countries: the Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and Tanzania.
Therefore, if it is a population explosion, it is not a global phenomenon but more or less local phenomena. However, this will do very little to help us solve this problem.
In some countries and regions, data on the size of their populations is inaccurate, uncertain or completely missing. The date November 15, 2022 and the figure of eight billion inhabitants of the Earth must therefore be taken with a grain of salt. It is more of a symbolic milestone. But it’s also a pretty good opportunity to think about the state and future of the world in which we live and in which the generations that will come after us will live.
