World Population In 2050 To Explode To 9 Billion, Africa Contributes 49%

[Haris]

World Population Expected To Reach 9 Billion

The world population is expected to reach nine billion in 2050, experts said.
For the next fifty years in 2100, it is expected to climb to another billion,
making it to ten billion. This is based on a review article by Professor David
Bloom, which was highlighted by the Harvard School of Public Health press
release. At present, the global population for year 2011 is expected to top
seven billion.

World Population Growth Geographically Uneven

Based on the report, the world population growth depends on the
geographical location. Hence, world population growth is geographically
uneven. A certain illustration would the countries of Japan and Germany
where population growth is controlled and slow. Thus, their populations will
stay constant, or possibly even decrease. For the years to come, Japan
and Germany could experience a demographics crisis as the elderly begin to
outnumber the young. As a result, fewer young people will be caring for
the old, which is a fearful situation for these countries.

Population Expected To Explode In Developing
Countries

Populations in developing countries are expected to explode, according to
reports. The continent of Africa is expected to have the highest figures in
population increase. The population of Africa is to rise to 1.1 billion. This is
49% of the global projected growth in 2050. Professor Bloom went on to
say that by the time the year 2050 approaches, the developed world is
estimated to have contributed only 3% of the projected global population
growth. This scenario is alarming, but the dangers will be prevented if
immediate action is taken.

Challenges In Population Growth

World population growth carries with it some problems that are inevitable.
This includes the lack of supply of food, water, housing and energy, said
Professor David Bloom. On the contrary, Professor David Bloom clarified
that the earth isn’t dying. The earth could still sustain the needs of the
population and the resources are still available to consume to cater the
needs of the exploding population. This report was confirmed by
agricultural scientists. According to the agricultural scientists, the earth
has a vast arable land to be used by the people. Based on the study, the
world’s population would fit in the state of Texas. However, certain
problems will be expected to occur like starvation, overcrowding, resource
mismanagement, corruption and many more.


In this article you learned that the world population is getting bigger and
bigger. In year 2050, the world’s population is expected to explode at 9
billion. Africa contributes to the expected growth of population in 2050 by
forty-nine percent. Notwithstanding the belief that the earth is dying and
could no longer sustain the needs of the people, a study by Professor
David Bloom clarified that the earth has enough resources to cater the
expected population growth in 2050.

Population to Bulge, But Will
Hit Ceiling

Speculation on population numbers raise questions about
whether the planet can sustain us all.

• The world’s population is expected to hit seven billion this year.
• By 2100, there will likely be more than 10 billion people living on Earth.
• After 2100, the population level will probably plateau.

The world's population is on track to hit seven billion this year, which is
double the number of people that lived on Earth in the 1960s, but far from
what the future holds. By 2100, according to recent projections by the
United Nations, we’ll hit the 10 billion mark.

Those numbers, which are drastically larger than anything the Earth has
experienced before, have sparked concerns about how all of those people
will impact the world. They have also raised questions about whether the
planet can sustain us all in the first place.

There may, however, be at least some end in sight to the relentless
swelling of population pressure. Around the end of the century, many
demographers believe, the global population will gradually level off.

Researchers can't predict with certainty exactly when that will happen and
at what level. Also up for debate is how the current level of population
growth will impact the environment, the economy and quality of life.

Overall, though, the level of rapid population growth we are experiencing
today cannot be considered a good thing, said John Bongaarts, a
demographer at the Population Council, a research organization in New
York City.

In some parts of Africa, for example, population is doubling every 20 years,
making it impossible for communities there to keep up with the growing
demand for housing, roads, schools and health clinics. To many experts,
those kinds of issues highlight the need for a global-wide investment in
family planning programs that provide women education and access to
contraception.

"Every billion people we add to the planet makes life more difficult for
everyone and will do more damage to the environment," Bongaarts said.

"Can we support 10 billion people? Probably. But we would all be better off
with a smaller population."

The multiplication of people on the planet wasn’t always so explosive,
according to a series of papers in this week’s Science. Growth started to
accelerate with industrialization around 1750, said Ron Lee, a demographer
and economist at the University of California, Berkeley.

By 1800, global population reached one billion for the first time. It took
another 125 years to reach two billion. After that, though, numbers rose
from three million to seven million in just the last 50 years. The population
growth rate reached a peak of two percent per year in the mid 1960s,
before declining to today’s annual growth rate of 1.1 percent.

No one can predict the future, but the U.N. has done a good job in the
past of estimting population sizes for several decades forward. By 2050, its
predictions range from 8.1 billion to 10.6 billion. For 2100, projections range
from 6.2 billion to 15.8 billion.

"There's nothing magic about the 10 billion number," Lee said. "On the
other hand, there's pretty good agreement to expect something like this
leveling off."

Longer life spans and lower death rates help explain why population size is
growing at its current pace. But the variable that will make the biggest
difference in how many people will live on Earth 100 years from now is
fertility rate, or the number of babies that women give birth to.

If every woman had two babies, the world's population would remain
stable. Today, there is a global average of 2.5 births per woman -- down
from five in 1950. That comes with huge geographical variation.

In Japan, China and Europe, women are having fewer than two babies,
while women in many developing countries are still having five or more.
Ninety-seven percent of the projected population increase over the next
century is expected to happen in developing nations, according to a review
article in Science by David Bloom, of the Harvard School of Public Health in
Boston. Nearly half of the growth will be in Africa.

Women who matter more to society and are given access to education,
according to previous research, end up having fewer children. Informing
people about contraception and making it available also make a big
difference, and not just in places like Africa, where a disproportionately
large population of young people is exacerbating problems like school
overcrowding and unemployment. In the United States, Bongaarts said,
about 15 percent of births are unwanted.

Even as the global population begins to level off in the coming decades,
experts are already expressing concern about the environmental and
economic consequences of stuffing so many people onto the planet. Parts
of the world are running out of water. Prices of food and energy continue
to rise.

"It's not clear how this is going to sort out," Lee said. "That's what I’m
worried about."

It's not population growth that's the big problem.
It's our current unsustainable way of life that needs to change.

I heard that some scientist are tring to kill the half of the population by biological wapons :S.
But I am curious how big the population of Afghanistan would be in 2050. I hoope not that big becuase Afghanistan is so poor how are they gona feed them all if it gets biger. I know that now there are some 30 miljon peopel.

food is not a problem

yes there was this scientist who suggested we wipe out 90% of world population.

[AFG21]

Yes they say food is not the problem if you cultivate almost all the virtiel lands on earth you can have enough food for almost 50 Biljoen peopel on this planet, But all the rainforest and naure will be gone, so if you say food is not the problem I think it is. Because what is it worth to have a Earth whithout any nature. And it's not only the food but also other things like clothing houses and other stuff that peopel need that is not plenty for evereon if the population will increase.
