Until then, years of extremely high death rates were quite frequent. It is possible for very sparsely populated areas to be overpopulated if the area has a meagre or non-existent capability to sustain life e. The natural resources of a nation can be divided as renewable resources and non renewable resources. It can result from an increase in , a decline in the , an increase in , or an and depletion of resources. During this time, population of the world rose rapidly. Compared to the birth rates decades ago, the birth rates nowadays are almost double. Meaning Population Explosion refers to the massive and sudden rapid rise of Population among the human being.
We should fight the menace of population explosion on all fronts and on war footing. It is estimated that man in the Stone Age had an average life expectancy of only 17 years, while ancient Romans and Egyptians attained 30 years on the average. Prevention of the Population Explosion Awareness made by the government The government creates more awareness among our country. So we have a high birth rate. But according to all plausible scenarios, the number of 9 billion will be exceeded by 2050. We studied the effects of exposure to indoor air pollution from the use of cooking fuels on lung functions and respiratory symptoms in women aged 15-60 years.
Moreover, we should also include out influence towards the world as a whole. The present population explosion and baby-boom is a very serious problem. It leads to various problems like unemployment, migration of people to the towns and cities, etc. Apart from this variant, there are also high and low variants those relying on scenarios implying respectively an extremely high and extremely low growth of the population and a variant in which the fertility rates are fixed at the current levels. This attitude is necessary for effective birth control. According to Malthus population increases in geometrical progression while resources of sustenance increase only in arithmetical progression.
Food security is another area that needs attention. During the 1951 Census, the Population increased by 361 billion. Thirdly: because of the positive population momentum, the world population will certainly continue to grow in absolute figures, even though the yearly growth rate in percentages is already on the decline for several years. The waste generated by the population exceeds the ability to dispose of it faster than it is created. This crossing of the billion mark has shaken the government and the people of India to the bones. !! People were able to fight and cure deadly germs that once killed them.
Int Perspect Sex Reprod Health. Their fertility level has been below replacement levels for years. According to the most recent projections by the United Nations, the number of 8 billion will probably be exceeded by 2025, and around 2045 there will be more than 9 billion people. Within this group of developing countries, the group of least developed countries, the poorest countries so to speak, is growing strongly: from 830 million now, up to an expected 1. Based on that we can conclude that the population will keep growing even faster. The natural resources will soon get exhausted.
The existing world scenario paints a dim picture. The point of this story is that the current growth numbers are historically very exceptional and untenable in the long term. There are not enough residential places available in the urban areas to accommodate a huge number of people. In absolute numbers, the world population will continue to grow anyway for quite some time as a result of demographic inertia. In a world that currently wrestles with such serious problems as global warming, the thinning of the ozone layer, increasing crime rates, toxic chemicals in our food, and starvation in developing nations, each of which is at least partially due to growing world population, it's hard to imagine anyone opposing restraints on population controls. Less than 18% of the world population is responsible for over 50% of the global carbon dioxide emission Chakravarty et al.
In present India, Population is growing day by day. Additionally, developing countries remain largely dependent on exports of natural resources to generate economic dividends. Germany on the other hand has a negative or shrinking momentum: even if the younger generations of Germans would have a larger num ber of children than the generation of their own parents, the birth rate in Germany would still continue to decrease because fewer and fewer potential mothers and fathers reach the fertile ages. The literature concerning explanations for the decrease in fertility is vast and complex, but two factors emerge as crucial in this process: education and child survival. This comprises very poor countries such as Somalia, Sudan, Liberia, Niger or Togo in Africa; Afghanistan, Bangladesh or Myanmar in Asia; and Haiti in the Caribbean. Improvements in medical technology reduced the number of still births, immature deaths and mortality rate.
Environmental Problems With this huge amount of people living in a small region, it definitely affects the around it. Resource shortages, environmental disasters, multi-layered pollution, mass species extinction, soil erosion, the destruction of forest cover, high infant mortality rates, elevated crimes, inflation, and so forth are only some of the many negative consequences of overpopulation. The rapidly growing population has become a serious issue for India. The other factor, the evolution of the fertility rate, is much more uncertain but of critical importance in the long term. The belief of the society that, a son is essential in a family makes several families grow to undesirable and uncouth sizes.
