Current World Population

Scientific Challenges in the Coming Century. Due to the heavy concentration of Christians and Muslims in this high-fertility region, both groups would increase as a percentage of the global population.

Estimates of the global size of these faiths generally come from other sources, such as the religious groups themselves.

Until the s, seven out of ten children died before reaching reproductive age. Please see discussion on the linked talk page. Better to prepare for this likely future with a focus on preventive health, finding better ways to take advantage of the productive and other assets of older populations, and moving toward simpler and less energy- and resource-intensive lifestyles than today's.

The emissions of carbon dioxide and other greenhouse gases give us a good indication of how high consumption is in a city. This has not currently been addressed by the foreign policy of many nations.

Former intern Joseph Naylor helped design maps, and David McClendon, another former intern, helped research global patterns of religious switching. This section of the globalissues.

That means that halophyte algae farmers could use solar-powered pumps to move water up from sea level.

Why Population Matters

In other words, while the planet might hold over 11 billion people by the end of the century, our current level of knowledge does not allow us to predict whether such a large population is sustainable, simply because it has never happened before.

But is that really the case? Is this not what triggered the Arab Spring and is likely to trigger Springs in the rest of, at least the poorer and most repressed countries?

Population growth has been so rapid that there is no real precedent we can turn to for clues about the possible consequences.

In the future, while this pattern is likely to continue, as resources get depleted and wasted in these wars hot and coldadditional conflicts and contention will arise through access to even more limited resources.

Most importantly, will we be able to feed 9. A Pew Research survey found that more than one-in-five U. India will retain a Hindu majority but also will have the largest Muslim population of any country in the world, surpassing Indonesia. Even better, algae require only a fraction of the land area of many other crops and can provide an excellent source of protein.

In the future, while this pattern is likely to continue, as resources get depleted and wasted in these wars hot and coldadditional conflicts and contention will arise through access to even more limited resources.

This will accelerate the diffusion of ideas and may even provide an opportunity to investors to bring to the market products and services to meet the aspirations of 7 billion consumers. Halophyte algae do not compete with food stocks for freshwater unlike corn.

Does population affect and put stress on the environment, society and resources? Much of the worldwide growth of Islam and Christianity, for example, is expected to take place in sub-Saharan Africa. Poverty is the number one health problem, in developing and developed nations alike.

Incensuses and surveys indicate, there were about 1. For this reason, many population projections do not include migration in their models. April 2, The Future of World Religions: While it might be an oversimplification to say the poor are victims, a lot of poverty, if not the majority is caused by factors which the poor themselves often have no control or choice over.

Effect of Growing Population

David Attenborough described the level of human population on the planet as a multiplier of all other environmental problems. With the global population at about 7. If current demographic trends continue, however, Islam will nearly catch up by the middle of the 21st century.

Human Population

Population projections are estimates built on current population data and assumptions about demographic trends, such as declining birth rates and rising life expectancies in particular countries. But working with researchers at the International Institute for Applied Systems Analysis in Laxenburg, Austria, the Pew Research Center has developed an innovative way of using data on past migration patterns to estimate the religious composition of migrant flows in the decades ahead.

Problems with power shortage and distribution. View image of Earth is not getting any bigger Credit: For alternative growth scenarios involving either switching in additional countries or no switching at all, see Chapter 1.

Byonly 30 percent of global energy is likely to come from alternative energy sources. For example, when death rates fell during the 19th and 20th century — as a result of improved sanitation, child immunizations, and other advances in medicine — allowing more newborns to survive, the fertility rate did not adjust downward, resulting in significant population growth.Apr 02,  · Between andthe number of people in the world aged 60 years or over is expected to grow by 56%, from just over million to nearly billion.

What is Overpopulation?

The world population is currently growing by approximately 74 million people per year. Current United Nations predictions estimate that the world population will reach billion aroundassuming a decrease in average fertility rate from down to The State of the World, Report from the Worldwatch Institute suggests that the global economy could be seriously affected by environmental problems, such as the lack of access to enough resources to meet growing population demands.

Some scientists believe that our advances in Science will help augment the demands of a growing population. They don’t believe that further population growth should be a cause of concern. By yearwe should be reaching a population between 8 to 10 billion. In general, conservationists and scientists are extremely worried about what the world's animal populations may look like if the human population grows to 11 billion.

Human overpopulation

Instead, the world is looking at a different problem - Negative population growth - this leads to a lopsided population, with more seniors than young people. And as the population ages, there isn’t enough young people to .
