An analysis of earth population growth problem
However, this outcome has been challenged or even bluntly denied in the afore mentioned special issue on sustainability.
This shows historical data, but also projections to based on the UN's medium growth scenario. The demographic transition describes changes over the course of socio-economic modernization. If the fertility rate stays below 2 children per woman then we will see a decline of the population size in the long run.
The main goal is to join economic growth and environmental preservation, according to the conclusion of a liberal view on sustainability. In the first place, very substantial declines in some European countries antedated the invention and mass manufacture of contraceptive devices.
The afore mentioned demograph Kaufmann argues in the same way, by proposing tax reduction for parents raising children on one hand and higher taxes for childless couples on the other. Finally, the social and economic changes characteristic of industrialization and modernization of a country are accompanied by and reinforce a rise of secularism, pragmatism, and rationalism in place of custom and tradition.

Stud Fam Plann. Population composition The composition of a population can also affect the surrounding environment. In the middle of the 21st century the number of births is projected to reach a peak at million and then to decline slowly to million births by They may also be forced to deplete scarce natural resources, such as forests or animal populations, to feed their families. The chart below shows the birth and death rates in England and Wales over the span of nearly years. It is expected to be lower in The IPAT equation is not perfect, but it does help to demonstrate that population is not the only or necessarily the most important factor relating to environmental damage. This is an extraordinary moment in global history. As we can see, a growing gap opens up between the birth and death rate after , creating a population explosion. In the map below we see country populations across the world through to the year In the many millennia up to that point in history very high mortality of children counteracted high fertility. As a consequence, the basis of the birth pyramid will become smaller and smaller. The decline in French births began late in the 18th century and the downward courses of the birth and death rates during the 19th century were more or less parallel.
Global sustainability, as concluded in an earlier special issue on sustainable development1, requires a different type of society, a different type of thinking and a different distribution of natural resources. Life expectancy has increased by approximately 20 years since In reality, there is no single, easy solution.
Why then is global population growth not coming to an end yet? It is shown in the schematic figure below.

They run the risk that rapid population growth and adverse age distribution would themselves prevent the achievement of the very modernization they count on to bring the birth rate down. Related Feeding a hot, hungry world Earth Climate change and human health Earth More food, cleaner food—gene technology and plants Tech. The total fertility rate — the number of births per woman in the reproductive age bracket — is only one of two drivers that matter here. Such rapid population growth, which is out of proportion to present and prospective rates of increase in economic development, imposes a heavy burden on all efforts to improve human welfare. This time it is our aim to take the rapid growth of the world population into consideration as well; this background problem fails to receive any sufficient attention up till now. The rates of population growth of the various countries of the world are, with few exceptions, simply the differences between their birth rates and death rates. Paul R. This also means that the extended family with many children, that we often associate with the past, was only a reality for glimpse in time.
Meanwhile, Indonesia — the most populous country in Southeastern Asia — is projected to reach its peak population in
