During —, the net number of international migrants to more developed regions is projected to be 98 million. Birth rates are now falling in a small percentage of developing countrieswhile the actual populations in many developed countries would fall without immigration.
Following this came the industrial revolution. Most developing nations have large number of people who are illiterate, live below the poverty line and have little or no knowledge about family planning. It is therefore important for parents and teachers to shed their old inhibitions and make their kids or students aware of solid sex education.
Over the past years, the global population has multiplied sevenfold Overpopulation. The first of these is the depletion of resources. Growing advances in technology with each coming year has affected humanity in many ways. Imparting sex education to young kids at elementary level should be must.
The Earth can only produce a limited amount of water and food, which is falling short of the current needs. Medical science made many discoveries thanks to which they were able to defeat a whole range of diseases. Until the s, seven out of ten children died before reaching reproductive age.
It causes more diseases to spread and makes them harder to control. Today, that rate has lowered to 7. Overpopulation can further be viewed, in a long term perspective, as existing when a population cannot be maintained given the rapid depletion of non-renewable resources or given the degradation of the capacity of the environment to give support to the population.
Starvation is a huge issue facing the world and the mortality rate for children is being fuelled by it. The effects listed on this page are just some of the main problems associated with or exacerbated by human overpopulation.
Elevated Crime Rate As human overpopulation drives resources and basic necessities, such as food and water, to become scarcerthere will be increased competitiveness for these resources which leads to elevated crime rates due to drug cartels and theft by people in order to survive.
As farmers begin to use more pesticides and chemical fertilizers to try to increase yields, those chemicals can create water pollution.
The invention of vaccines and discovery of antibiotics such as penicillin saved thousands of lives and were a key factor in unfettered population growth. Easily spread disease The closer people become, the easier airborne illnesses are spread. Animal overpopulation[ edit ] In the wild, overpopulation often results in growth in the populations of predators.
The population of 51 countries or areas is expected to be lower in than in As the number of annual deaths fell, while births remained constant, so the population increased.The Effect of Overpopulation on Public Health. The world population is growing at an alarming rate.
But overpopulation is seldom discussed as a public health issue. The effect of overpopulation on the world’s wildlife is also a major issue. As demand for land grows, so too does the destruction of natural habitats, such as forests.
Some scientists warn that if present trends continue, as many as 50% of the world’s wildlife species will be at risk of extinction. As population densities increase, laws, which serve as a primary social mediator of relations between people, will more frequently regulate interactions between humans and develop a need for more rules and restrictions to regulate these interactions.
Aldous Huxley predicted in that democracy is threatened due to overpopulation and could give rise to totalitarian style governments and it. Overpopulation: Causes, Effects and Solutions: Overpopulation is an undesirable condition where the number of existing human population exceeds the carrying capacity of Earth.
First and primary thing is space, that is density, demand for natural resources will increase in direct proportion to the rate of population increase.
The rate of competition of jobs increases, demand for food increases, and the rate of infectio. The effects of the Black Death are thought to have reduced the world's population, then at an estimated million, to between and million by The population of Europe stood at over 70 million in ; these levels did not return until years later.Download
