Indias Population Essay Example for Free

Indias Population Essay India with its 1.21 billion population occupies second place in the world next to China. India has about 17.5% of the world population with only 2.4% of the world area. The changes in the size and growth of India’s population are considered here in terms of two broad periods, namely Pre-Independence period and the Post-Independence period. The year 1881 is important in the sense that it was the year when the first census on a country wide basis was taken in India. Population of India: Pre Independence Period According to Herodotus (490 B. C.), India was one of the most populous countries in the world. Alexender’s army which invaded India in 327-326 B.C., found a large population. India’s first real empire under Chandragupta Maurya (321-297 B.C.) left records indicating the existence of a standing army of approximately 7,00,000 men. Only a very substantial population could have supported such a large army. The first national decadal census was conducted in 1881 recording a population of 225 million which declined to 251 million in 1921. The Population of India: Post Independence Period Till 1951, when the first census after independence was conducted, the decadal growth was around 13 to 14 percent, registering a gradual rise. 1961 recorded a growth of 21.5percent, which increased to 24.8 and 24.7 percent in 1971 and 1981 respectively. In 1991 the growth rate slightly declined to 23.6 percent. It is a matter of concern that the decadal population growth rate has declined to 21.2 percent in 2001 which further declined to 17.6 percent in 2011. It is estimated that by 2028 India will double its population and it will become the most populous country in the world by 2035. Population Planning in Five Year Plans : India is the first country of the world to adopt the population planning to control its population as an official policy. After an expansion of clinical services in the first two five year plans, the third plan which started in an environment of shock, changed its strategy to extension approach which continued in the fourth plan too. The fifth Five Year Plan (1974-1979) has been unique in the history of the country as a new Family Planning Programme was opted during this. The National Population Policy Statement of April 1976 was the most articulate renunciation of the official policy. The following were its main features: 1. Increase the legal minimum age at marriage from 15 to 18 years for females and 18 to 21 years for males. 2. Freezing the population at the 1971 level for determining representation in Parliament and the State Legislatures up to 2000 A.D. 3. 1971 population was considered as the base for allocation of Central assistance to the State Plans. 4. Eight percent of Central Assistance to the States was to be linked with family planning programme performance. 5. The allotment of houses and loans were to be linked to family size. The eighth Five Year Plan (1992-1997) set the population goal for achieving a net reproductive rate of one by turn of the century and zero population growth by the year 2050 A.D. The immediate objective of the National Population Policy 2000 was to address the unmet needs for contraception, health care infrastructure. In the eleventh Plan which started in 2007, it was emphasised that only through a multi- pronged strategy of combining fertility control measure and welfare measures with population education for people at large and youths in particular along with making school education up to age 14 free and compulsory and reducing drop outs at primary and secondary school levels below 20 percent for both boys and girls, the population goal of India can be achieved. For the twelfth Five Year Plan (2012-2017), it has been emphasised to improve healthcare infrastructure and implementation of making education compulsory for all the children till the age of 14. Adverse Consequences of Population Explosion: The population explosion, which is undermining all our efforts towards development of the country, is perhaps the single most pressing problems faced by it. The recent census has revealed that while there has been a decline in the rate of growth of population, still the growth rate of 1.7 percent per annum is quite high. If the population growth continues as at present, the country will have such a large population which would be virtually unmanageable. Despite best efforts, it would not be possible to provide even the basic necessities of life to the people at large. Such relentless population growth would also create havoc to our environment and will lead to ecological crises. It has considerable impact on natural resource uses and socio economic development. Rapid population growth will also mean increased urbanization, which may lead to more diseases and further deterioration of water and sewer systems and various pollutions. Future Directions: There cannot be only one miracle formula which will cover the entire country. The main barriers of population control such as poverty, illiteracy, son – preference etc. need to be removed. Since these barriers operate simultaneously at different levels, it is difficult and rather impractical to assign priorities to them. It is obvious that increase in literacy and educational status of women will have positive effects on population control, infant mortality, health care, nutrition, sanitation and hygiene. Further, it will result in raising the age of marriage, improved knowledge of contraception and adoption of small family norm. Population control and Family Welfare Programme need to have a national consensus, cutting across political, religious and cultural differences. It should be based on active community participation and has to be transformed from a Government Programme into People’s Movement. Population education should be part of school and college education. It should also form an important ingredient of adult education and non-formal education. Communication strategies should be so devised as to be effective enough to bring about attitudinal changes and dispel apathy, ignorance and misgivings about family planning and small family norm. In conclusion, it is important that people not only have proper health services which are both accessible and available, but they should also have access to employment which will provide them with financial security. People must be made educated and have awareness, as education itself is the best contraceptive. People should realize that having a girl child does not mean carrying a heavy burden.

Coal Chemistry and Technology Essay example -- Coal Research Paper

1. Coal formation Coal was formed from remains of plants from several hundred millions years ago partially decomposed. These remains were settled in regions where waterlogged or swampy regions prevailed. These conditions avoid complete decomposition making possible the gradual peat formation. Peat is not considered coal actually, but is an essential step to coal formation. This formation process is called "coalification" and it is essentially a progressive change from peat to anthracite passing through different types of coals. This process not only depends on the time, but also on temperature and burial pressure (Speight 1983). Schematic representation of the coalification process (Speight 1983) 2. Coal Classification Coals can be classified by its "rank". The rank of the coal can be defined as the degree of alteration that coal experiments during the coalification. On the one hand there are Lignite and sub-bituminous coals which are Low rank coals. These have a lower content in Carbon, are lighter and have higher moisture levels. On the other hand there is Bituminous coals and Anthracite which are high rank coals. They have a higher content in carbon which means they have more energy content. They have lower moisture levels and a more vitreous appearance (University of Kentucky, 2012). â€Æ' 3. Coal Composition Coal is an organic sediment which can be described in several ways. The most common way is in terms of the elemental composition. J. G. Speight, (1991) suggested that coal can classified on the basis of the general formula: Cn Hm Nx Oy Sz (where n, m, x, y and z are number of atoms of each element) Coal is not a homogeneous material.

Movie Review: The White Balloon Essay

Jafar Panahi’s movie entitled â€Å"The White Balloon† is a depiction of social reality in these present times within the eyes of a young girl protagonist. The conflict of the story is simple as well as the resolution and its setting. The main problem of the protagonist is her likeness to buy a fish but she does not have any amount of money in her pocket. What she did was she took her mother’s last money and went to the store but while walking to the store, the girl lose her mother’s money that brought fear and anger within her. At the end of the story, there is no concrete solution to the conflict but the protagonist made her own way of obtaining the money to buy the fish.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Like what other critics and analysts said towards this film, there is no need to impose complex conflicts to make each story a good one. As long as there are complete scenarios and interpretations of things, everything would be better than the others. This is what Panahi did in this movie. He only took the courage to discuss and illustrate the life of Iranians in a typical country of Iran. Though it is more on the simple aspects of Iranian tradition, there is a combination of twist and turns that will bring its audience to the mood of waiting for the next situation.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In my own perception and point of view regarding the issues and topics that were tackled in the movie is that the director has no direct attack towards the resolution of the conflict. He is already satisfied with the illustrations and discussions of Iranian life but there is no form of resolution to the conflict. The protagonist’s problem was not a personal problem but a social problem that should not be taken for granted. It means that the director itself should not take this for granted if he wanted to analyze the situation of Iranian people especially in the cases like this where the main character is a child who always seeks for answers in every question.

Evolution Drives The Diversity And Unity Of Life - 1674 Words

Big Idea 1- The process of evolution drives the diversity and unity of life Natural selection is evolutions driving mechanism. Evolution is â€Å"the process by which different kinds of living organisms are thought to have developed and diversified from early forms during the history of the earth.† Darwin s theory states that inheritable variations exist within individuals in a population. This big idea has impacted human life and evolution in many ways. With natural selection as its major mechanism, according to Darwin’s theory, competition for limited resources results in differential survival. People with more favorable phenotypes are more likely to survive and reproduce, which passes their traits onto future generations. This big idea relates to the other big ideas because you need to transmit the important information, as in genes and traits that an organism will pass on to future generations so that they can eventually evolve. This is the process of natural selection. Alteration in the gene pools of populations can be caused by naturally occurring catastrophic or human induced events. It can also be caused by random environmental changes. In order for species to survive, they need a diverse gene pool because environmental changes can readily change. Species may not be able to survive in new environmental changes without a diverse gene pool and phenotype diversity. Sources of genetic variation can provide new genes and combinations of alleles that grant new phenotypes.Show MoreRelatedEvolution Of A Common Single Celled Origin1278 Words   |  6 Pages In the course of AP Biology, there are four â€Å"Big Ideas†.
