TheWorldCounts, 15 June, A billion planets, One Earth… How will our continuously growing population affect our way of life, our planet, our environment?
Global life expectancy at birth is expected to continue rising from 65 years in — to 75 years in — Just 10, years ago there might have been no more than a few million people on the planet. For example, the use of tools, such as bow and arrow, allowed primitive hunters greater access to more high energy foods e.
Many countries have high population growth rates but lower total fertility rates because high population growth in the past skewed the age demographic toward a young age, so the population still rises as the more numerous younger generation approaches maturity.
Until the s, seven out of ten children died before reaching reproductive age. Water scarcity is a growing concern. Today, starvation is caused by economic and political forces rather than a lack of the means to produce food.
Birth rates are now falling in a small percentage of developing countrieswhile the actual populations in many developed countries would fall without immigration. 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.
Overpopulation is caused by number of factors. Many feel as has been the case throughout history that the major international wars to be fought in the future will continue to be over natural resources.
This fits with a general pattern that has played out over the past century or so, explains Will Steffenan emeritus professor with the Fenner School of Environment and Society at the Australian National University. The information understood so far provides valuable insights and is very important to consider, nonetheless.
Developing nations face the problem of overpopulation more than developed countries, but it affects most of the Earth as of now.
The emissions of carbon dioxide and other greenhouse gases give us a good indication of how high consumption is in a city.
As we humans are more inclined towards money, this may produce some positive results. In the past fifty or so years, the growth of population has boomed and has turned into overpopulation. That will just postpone the day of reckoning and make the problem worse by continually enlarging the population of all ages.
One least-understood problem about such insane growth is the potential for regional wars to control water resources, for example, war between Egypt and Ethiopia.
In the early 20th Century, the global population problem was as much about the fertility of soil as the fertility of women A UN report summarised 65 different estimated maximum sustainable population sizes.
View image of Copenhagen: That projected population growth raises a host of questions about the future of humanity and the planet we inhabit. One good model of over population is India.
Satterthwaite says that most of the growth over the next two decades is predicted to be in urban centres in what are currently low and middle-income countries. So Steffen suggests that we should stabilise the global population, hopefully at around nine billion, and then begin a long, slow trend of decreasing population.
But can we really single out population growth in this way? Environmental Degradation Facts Is the concern real? Conflicts over water are becoming a source of tension between countries, which could result in wars. Europe for example, has higher population densities than Asia.
As population of this world is growing at a rapid pace, raising awareness among people regarding family planning and letting them know about serious after effects of overpopulation can help curb population growth.
Better care, education and rights for women mean that children should also benefit. If the number of children born each year equals the number of adults that die, then the population will stabilize. The population of 51 countries or areas is expected to be lower in than in It is therefore important for parents and teachers to shed their old inhibitions and make their kids or students aware of solid sex education.
However, when talking about overpopulation we should understand that there is a psychological component as well. The rest faced poverty and would give birth to large families to make up for the high infant mortality rate.
Ivanova and her colleagues argue the consumers themselves are just as responsible. Shortage in medical facilities and services.
In there were 83 cities with populations exceeding one million; but by this had risen to agglomerations of more than one million. Tax Benefits or Concessions: This will lead to intracountry and regional instability that will in turn reinforce extremist forces and perpetuate poverty and lack of security.
This has led to less investment in health, education and other basic services things that have led to a better quality of life in Europe after the second world war.If you look at the population/time graph of the world population, you'll see a J curve that is almost flat for thousands of years, and then, aroundsuddenly takes off.
If you match that to a similar graph of oil production and consumption, they. The United Nations estimates that the world population at the end of the century will be around 11 billion, and many fear that the planet's natural resources are insufficient to accommodate such.
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.
While public concern about rapid population growth has subsided in recent decades, world population is still growing at about 80 million people a year, or aboutpeople per day. If current trends persist, there will billion more people on the planet by mid-century, bringing the total to about billion.
Inthe United Nations estimated that the world's population was growing at the rate of % (or about 75 million people) per year and according to data from the CIA's World Factbook, the world human population currently increases by every minute.
Asked whether or not the growing world population will be a major problem, 59% of Americans agreed it will strain the planet’s natural resources, while 82% of U.S.-based members of the American Association for the Advancement of Science said the same.Download
