Question 1.Answer the following questions.
(i) Why are people considered a resource?
(ii) What are the causes for the uneven distribution of population in the world?
(iii) The world population has grown very rapidly. Why?

Answer.
(i) Human beings are the most important resource of a nation. They are significant because had they not utilised their brains, the other resources of nature would not have found any utility. In other words, human resource is the ultimate resource.

(ii) Population density depends on the climate conditions and topography of the place, like few people live in high latitude areas, tropical deserts, mountainous ‘terrains, and forest areas,whereas a large number of people reside in plains. Fertility of soils, availability of fresh water, minerals are other major geographical factors behind this. Some social factors that boost the density of population in a region are better housing, education and health facilities. Places with cultural or historical significance are usually populated. Employment opportunities are another attraction for large chunks of population.

(iii) Because of the better food supplies, increase in medical facilities, reduced death rate, birth rate almost remaining the same.

  • The difference between birth rate and death rate is called natural growth rate. This natural growth is high due to better medical and food facilities leading to growth in population.
  • Many people move from one country to another due to various reasons. This also leads to increase in population of the countries having his immigration.
