Aging of population (also known as demographic aging‚ and population aging) is a summary term for shifts in the age distribution (i.e.‚ age structure) of a population toward older ages. A direct consequence of the ongoing global fertility transition (decline) and of mortality decline at older ages‚ population aging is expected to be among the most prominent global demographic trends of the 21st century. Population aging is progressing rapidly in many industrialized countries‚ but those developing

shortages‚ soil exhaustion‚ loss of forests‚ air and water pollution‚ and degradation of coastlines afflict many areas. As the world’s population grows‚ improving living standards without destroying the environment is a global challenge. Most developed economies currently consume resources much faster than they can regenerate. Most developing countries with rapid population growth face the urgent need to improve living standards. As we humans exploit nature to meet present needs‚ are we destroying resources

Population Viability Analysis Introduction Over the last few lectures we’ve talked about the stochastic threats to persistence in small populations. We identified five classes of threats and some of their qualitative properties: 1. Genetic stochasticity — Not a problem in populations with Ne greater than a few hundred. Therefore‚ not likely to be a problem in populations large enough to buffer environmental stochasticity 2. Demographic stochasticity — Unlikely to be a problem in populations with

number of people. If the world population continued to grow at the current rate‚ the earth would not be able to sustain its population and the number of people will decrease. In Dr. Coy’s lecture about Understanding Growth‚ she said‚ “From the time of the earliest humans until about 10‚000 years ago‚ the world population probably never exceeded 2 million. The human population grew faster after the invention of agriculture. After the industrial revolution‚ the human population began to follow an exponential

The Population Bomb The continuous increase of population in the world has become a major problem to planet earth. Oftentimes‚ it is referred to as the population bomb owing to the adverse impacts it creates on the world today. Such population explosion leads to social‚ economic and environmental problems. This prompted the enactment of global protocols‚ regional agreements and localized legislations which are all geared up towards resolving mounting social‚ economic and environmental problems

Control of Population Growth by the Government Population growth is the increase in the number of people who live in a specific area. Population growth has a huge impact of economies‚ education‚ etc.‚ therefore the levels of population growth is a huge concern around the world. There have been a number of countries that have been encouraging the population to produce more offspring‚ such as Shanghai. However‚ these policies are just to motivate the population to have more babies and there are always

the world population is distributed? Key issue 1 -we can understand how population is distributed by identifying two basic properties. 1. Concentration 2. Density Population concentrations -two thirds of the world’s population is clustered in 4 regions: East Asia‚ South Asia‚ Southeast Asia‚ and Western Europe. - The clustering of the world’s population can be displayed on a cartogram‚ which despites a countries size according to its population not its land area.
