There are more and more inhabitants in the world. Currently there are almost 8 billion people, and by 2050 it is expected that there will be 10 billion in total.
The problem is that there is already a lack of control. Having more than 10 billion inhabitants on the planet will cause not only social problems, but also environmental ones.
In a study done in 2018, the nine countries that will grow the most in the coming years are: India, Nigeria, Pakistan, Democratic Republic of the Congo, Ethiopia, Tanzania, Indonesia, Egypt and the United States. They alone will cause more than half of the births that will occur worldwide in the coming decades.
Population growth
Overpopulation will increase the France Mobile Number List problems we have with climate change, global warming and resource depletion, there will also be greater pollution and even nutrition problems.
Population growth continues in underdeveloped countries according to United Nations data collected by CNN: while globally the number of births has fallen from 3.2 babies in 1990 to 2.5 per woman today, there are regions that will directly double its population, is the case of the countries of sub-Saharan Africa.
Furthermore, the increase in life expectancy has meant that there are more people of adult age than children under 5 years of age.
On the other hand, The World Population Prospects 2019: Highlights estimates that in the next thirty years the world population will add two billion more people than the current figure (7.7 billion) and that, by the end of this century, The planet will have around 11 billion.
India is expected to show the largest population increase between now and 2050, overtaking China as the world's most populous country around 2027, which is why it, along with eight other countries (Nigeria and Pakistan, followed by the Democratic Republic Congo, Ethiopia, Tanzania, Indonesia, Egypt and the United States of America), will account for more than half of the population growth.
There is a slowdown in the global fertility rate. As mentioned above, in 1990, the average number of births per woman was 3.2.
By 2019, it had dropped to 2.5 births per woman, and by 2050, it is projected to decline to 2.2. But a fertility level of 2.1 births per woman is necessary to avoid long-term national population decline (in the absence of immigration).
Based on it, the population size of more and more countries is decreasing since 2010.
Between now and 2050, the decline is expected to expand to fifty-five countries, which will see their populations decline by 1% or more, with almost half of them experiencing a drop of at least 10%.
In some cases, the decline in population size is forced by high emigration rates, as this has become one of the main reasons for population change in certain regions (Bangladesh, Nepal and the Philippines due to the demand for migrant workers, and Myanmar, Syria and Venezuela due to violence, insecurity or armed conflict).
By 2050, one in six people will be over sixty-five, compared to the current figure of one in eleven. Some regions will see the proportion of older people double over the next thirty years, including North Africa, Asia and Latin America.
This means that by 2050, a quarter of the population in Europe and North America could be sixty-five years old or older. Greater financial pressure is thus expected in countries in the coming decades, with increased spending on public health systems, pensions and social protection.
At the same time, recent declines in fertility mean that the working-age population (between twenty-five and sixty-four) is growing faster than other age ranges, which could improve the chances of faster economic growth.
