Land, Soil, Water, Natural Vegetation and Wildlife Resources

Question:

Answer the following questions.
(i) Why are resources distributed unequally over the earth?
(ii) What is resource development?
(iii) Why are human resources important?
(iv) What is sustainable development?
 

Answer:

(i) The distribution of resources depends on various factors such as physical nature of the place. The physical factors include terrain, climate, height above sea level, etc. Since these factors vary in different parts of the world, resources are pot distributed over the earth.
(ii) Resource development is the method of utilising our intelligence in order to improve the quality, usability and utility of a resource.
(iii) Human resources are important
because they have an intelligent mind which can make best use of nature to create more resources. Had humans not been there, different substances would not have been resources. Their utility can only be realised by human beings.
(iv) We should use resources in such a balanced way that we satisfy our needs as well as conserve them for future. This concept is called sustainable development.
