The World Population Has Grown Very Rapidly. Why?

The death rate has decreased as a result of increased food supply and improved medical services, resulting in the rapid growth of the global population. Furthermore, unlike the death rate, the birth rate has stayed relatively constant. Thus the world population has grown very rapidly.


Question 2 :

Why are People Considered As Resources?

Answer :

People are considered resources because they can produce new resources with their demands and capabilities. Nature's abundance is only valuable when people discover it and put it to good use.

Question 3 :

What are the Causes for the Uneven Distribution of Population in the World?

Answer :

The world's population distribution is unequal. Some parts of the city are densely populated, while others are sparsely populated. This unequal distribution can be attributed to a number of factors:

(i) Geographical Considerations: Topography, mineral and freshwater resources, a favourable climate, and soil fertility are only a few of the factors that influence population dispersion. Indo Gangetic Plains, for example.

(ii) Social and Cultural Factors: Population density is higher in areas with better housing, education, and health care. Consider the city of Pune. People are drawn to places of religious and cultural significance, such as Varanasi and Jerusalem.

(iii) Economic Factors: Communities with more industry, transportation, and communication facilities have greater job prospects. People are drawn to these locations for the reasons stated above, such as Mumbai and Osaka.

 


Question 4 :

Discuss the Role of Any Two Factors Influencing Population Change.

Answer :

Population change is the phenomenon of determining whether the population has increased, decreased, or remained constant. Natural growth and migration are the two most important elements. The difference between the birth and death rates is the natural growth rate. The number of live births per 1000 people is the birth rate, while the number of deaths per 1000 people is the mortality rate. The natural reasons for population change are as follows:

(i)The population rises when the birth rate surpasses the death rate.

(ii)The population declines when the mortality rate exceeds the birth rate.

The population remains constant when the two rates are equal. As a result, birth and death rates have an impact on population balance. People can travel both within and between countries. Migration is another factor that influences population change.
