1. With fewer children, parents can save more for their education and provide them with the best possible opportunities.
2. In a small family, having fewer members means less spending, which allows the family to save more for the future. These savings can help them build a house, buy a car, or meet other important needs.

Que-3: List three major landmarks in human history which contributed to the sudden rise in population of the world.

Ans: The three major landmarks in human history which contributed to the sudden rise in population of the world were:

1. Tool making revolution.
2. Agricultural revolution.
3. Scientific industrial revolution.

Que-4: What is meant by family welfare centres? What is the symbol of family welfare in our country?

Ans: The department that plays an important role in population control and provides guidance and support for family planning is known as the Family Welfare Centre. These centres can be located in hospitals, dispensaries, and similar institutions. The inverted red triangle is the official symbol of family welfare in India.

Que-5: Sterilisation in men means preventing the flow of sperms into the seminal vesicles by cutting and ligating the vas deferens. Can there be a corresponding operation made in women? If yes, where?

Ans: Yes, a similar surgical procedure can be performed in women. It is called a tubectomy. In this operation, the abdomen is opened and the fallopian tubes (oviducts) are cut or tied with a nylon thread to block the passage of the egg. A diagram of the tubectomy procedure is shown below:

Que-6: Write the full forms of the following abbreviations:

(a) IUDs
(b) MTP

Ans:
(a) IUDs:  Intra-Uterine Devices
(b) MTP : Medical Termination of Pregnancy

Que-7: Explain briefly the relationship between poverty and population and how one affects the other.

Ans: Poverty and lack of access to education often lead to higher birth rates and overpopulation. Rapid population growth reduces per capita income and overall well-being, which in turn increases poverty. In fact, poverty is considered one of the major causes of overpopulation.
Poverty and population growth have been closely connected ever since the major revolutions changed the world. Each affects the other. Poverty persists mainly due to illiteracy and traditional beliefs among economically weaker sections. Because these beliefs are deeply rooted, many people in these groups see children as a gift from God, a sign of prosperity, and additional helping hands to support the family income. As a result, they continue to have more children without realizing that their difficult living conditions cannot support them, ultimately adding more individuals to the already burdened cycle of poverty.
Thus, as the population increases, poverty deepens, and the overall quality of life declines.

Que-8: Mention two reasons for the rapid increase of population in India.

Ans: Two reasons for the rapid increase of population in India are:

1. Illiteracy — Most of the rural population which forms the bulk of our society is still illiterate, ignorant and superstitious. They also do not know the functioning of the human reproductive system.
2. Traditional Beliefs — Among the people from lower strata of the society, children are regarded as a gift of God and a sign of prosperity. Therefore, they make no effort to avoid pregnancy.
