Changes in atmospheric composition and consequent global warming.
Indeed our very success going forth and multiplying, paired with our ability to extend our life expectancy, has meant that we are perpetually pushing the limits of the resource base that supports us. Today our population tops seven billion. While better health care and medicine along with advances in food production and access to freshwater and sanitation have allowed us to feed ourselves and stave off many health ills, some so-called Neo-Malthusians believe we may still be heading for some kind of population crash, perhaps triggered or exacerbated by environmental factors related to climate change.
Of course, the immigration that continues to fuel population numbers in developed countries is coming from somewhere.
Also fertility rates in Africa continue to be among the highest in the world, as many countries there are growing fast, too.
Poverty and health problems due to poor sanitation, lack of access to food and water, the low social status of women and other ills continue to cripple these regions.
Globally, the United Nations estimates that the number of humans populating the planet in will range from as few as 6. Meanwhile, other researchers confirm the likelihood of world population levels flattening out and starting to decline by according to the lower UN estimate. To wit, the Austria-based International Institute for Applied Systems Analysis IIASA recently unveiled research showing that if the world stabilizes at a fertility rate comparable to that of many European nations today roughly 1.
It is difficult to say which way the global population pendulum will swing in centuries to come, given ever-changing cultural, economic and political attitudes and the development demographics they affect. As such the jury is still out as to whether human overpopulation will become a footnote in history or the dominant ill that stands in the way of all other efforts to achieve sustainability and a kinder, gentler world.Indeed, population numbers are still growing in many of the world’s developing countries, including the world’s most populous nation, China, and its close rival, India.
Due to over population infant mortality and low life expectancy are problems all around the world with rising numbers, they are becoming bigger issues.
For both there are some solutions but not all the solutions work. Infant mortality is the death of children under the age of one year. Life. Among the least developed countries, where life expectancy today is just under 50 years, it is expected to increase to 66 years by – The population of 51 countries or areas is expected to be lower in than in Overpopulation is an undesirable condition where the number of existing human population exceeds the carrying capacity of Earth.
Overpopulation is caused by number of factors. Reduced mortality rate, better medical facilities, depletion of precious resources are few of the causes which results in overpopulation. Due to over population infant mortality and low life expectancy are problems all around the world with rising numbers, they are becoming bigger issues.
For both there are some solutions but not all the solutions work. Infant mortality is . India also has enormous problems with overpopulation.
The current population is over a billion, but India does not have the large land mass that China has. Low birth rate due to the inability of mothers to get enough resources to sustain a fetus from fertilization to birth, miscarriages Low life expectancy in countries with fastest growing.
