FAR EASTERN FEDERAL UNIVERSITYSCHOOL OF BIOMEDICINE”EFFECT OF RAPID GROWTH OF OVER -POPULATION ON THE ECONOMY”BY:VENKATESAN THAMIZHARASANGROUP-2INTRODUCTION A Population is a group of interbreeding organisms in a specific region it is examined in terms of its variability, density and stability along with environmental and other processes and circumstances that affect these characteristics. Problems of population size and growth, resource utilization and depletion, and environmental deterioration must be considered on a global basis. population control is obviously not a panacea-it is necessary but not alone sufficient to see us through the crisis. Population density is a poor measure of population pressure and redistributing population would be a dangerous pseudo solution to the population problem. “Excessive population growth may reduce output of individual worker, repress levels of living for the masses and engender strife.” RAPID POPULATION GROWTH: An increase in the number of people that reside in a country, state, county, or city.
To determine whether there has been population growth, the following formula is used: (birth rate + immigration) – (death rate + emigration). The world’s population growth has touched a peak of 7.3 billion in 2015, with developing countries accounting for some 5.4 billion, and economically advanced nations accounting for 1.6 billion, “population explosion is the result of falling mortality rates and contuning.
PROBLEMS THAT AFFECT THE WORLD TODAY BY OVER-POPULATION: The problems we have today such as war, crime, food shortages, water shortages, water pollution, and air pollution; global warming and unemployment are the effects of over-population. The more people there are the more resources consumed and the more waste created on the land. The increased population causes poverty problems and deforestation and etc, According to our survey is the first country which has increased-population, so most of the peoples may change their places for their employment . If the population grows people will suffer to get their daily needs like food, cloths, shelter. And the forest is also being destroyed mainly due to over-population. The peoples will destroy the forest for constructing building and mostly constructions. Due to over population each and every people use motor bike, and other vehicles and burning fossil fuels that creates global warming and changes in climates and also many environmental degradation. And it may also possible for couple who are unable to conceive to undergo fertility treatment methods and have their own babies.
Today there are effective medicines which can increases the chance of conception and lead to rise in birth rate. Moreover, due to modern techniques pregnancies today are far more safer.Problems of Overpopulation:Explosion of Natural Resourcesif human population increases it causes exhaustible natural resources such as arable land, coral reefs, fresh water, fossil fuels, and wilderness forests continue to drop sharply. It leads to the way of competitive demands on the essential resources and contributes to an horrible decline in the quality of our life.For example, rainforests are being covered with 14% of the total earth’s surface. But now rainforests only cover about 6% of the earth’s surface and according to the scientists it has been gradually decreases after fourty years by the current rate of vegetation removal, logging, and deforestation.
In addition to environmental pollution, 30% of the ocean reefs have been lost because of acidification and global warming since 1980. More than half of the original wetlands and coastal reefs have been lostLoss of BiodiversityOverpopulation has seen continued encroachment into frontier forests, increased pollution, and destruction of many natural ecosystems that has greatly contributed to the mass decreased of species. The number of threatened species had been results to multiply worldwide whereas some have completely gone extinct or destroyed in our environment.
This is due to the human activities such as acidifying water systems, over-exploitation of natural resources, pollution, over-fishing, poaching, and the deliberate as well as the indirect destruction of natural systems necessary for the survival of different species. These human activities simply alter the natural process combined, thus, destroying the natural ecosystems supporting biodiversity.Emergence of New Pandemics and EpidemicsAccording to WHO(world health organisation), increased population is one of the leading causes of the speedy occurrence and urgent emergence of human diseases. Increased population causes social factors such as pollution, malnutrition, overcrowded living conditions, and lacking health care which makes poor communities vulnerable to infectious diseases.
It may also leads to many Diseases such as tuberculosis, malaria, HIV, and dysentery spread faster in overpopulated areas.REASONS FOR THE EXPLOSION: The main reason for slow and fluctuating population growth prior to early 1800’s was the prevalence in epidemiology disease such as small pox, mumps, and measles and scarlet fever. In addition, epidemics, diphtheria of diseases such as typhoid, cholera, jaundice, diphtheria and plague and chicken pox washed out many of the large number of adults and families. Most of the peoples where die due to attack of newly disease without discovery of the medicines. Reproductive rates were largely equalized by high mortality of peoples.
It causes spectacular reductions in mortality, especially among infants and children, so it causes increases in birth rate. Human population is to remain high in crowd. It entered in to exponential growth. After the new medicines and industrial revolution, the death rate is decreased and birth rate is increased, so the human population growth rate is high and results as over-population. People should subdivide their farms and lands among the children (or) intensifying their cultivations of existing land to increase production per unit area.
Increasing population especially affects women and children. Over-population causes effects to the environment both positively and negatively. CONCLUSION: Provide universal access to safe and effective contraceptive methods for both female and male preventing from over-population. With two in five pregnancies reported as mistimed or never wanted, lack of access to good family planning services is among the biggest gaps in assuring that each baby will be wanted and welcomed in advance by its parents. Guarantee education through secondary school for all, especially girls. In every culture surveyed to date, women who have completed at least some secondary school have fewer children on average and have children in future than do women who have less education. Eradicate gender bias from law, economic opportunity, health, and culture. Offer age-appropriate sexuality education for all students.
End all policies that reward parents financially based on the number of children they have. REFERNCE: Effects of rapid population growth on labor supply and employment- Bloom, 381-414. Bloom D.
