POPULATION GROWTH AND WORLD FOOD SUPPLIES
Answer the following questions.
(i) Which areas are most affected by incessant growth in population?
Ans. The incessant growth in population is causing serious economic problems in almost all continents. Great pressure is being placed on arable land, water, energy, and biological resources. The developing countries are the most affected areas by incessant growth in population.
(ii) Why are developing countries going to suffer more due to over population?
Ans. It is reported that all future population growth is going to take place in developing countries. The population growth reduces per capita income of the people because national income is divided by a big size of population. Thus developing countries are going to suffer more due to overpopulation.
(iii) What is the major cause of food shortage and malnutrition?
Ans. Overpopulation is the major cause of food shortage and malnutrition. Due to overpopulation, there is a shortage of fertile agricultural land, fresh water and fossil energy. The scarcity of these things decrease food productivity. Moreover, more people need more food.
(iv) How are water resources under great stress?
Ans. Due to overpopulation water resources like rivers, lakes and aquifers are under great stress because more people consume more water for agricultural, industrial, household, recreational and environmental activities.
(v) What is the effect of depletion of fossil energy?
Ans. The effect of depletion of fossil energy is that the prices of fuel i.e., oil, coal and natural gas are rising everywhere which is a massive setback for industries and transportation. Moreover, energy production is also reduced.
(vi) What is the limitation of improved technology?Ans. The limitation of improved technology is that it cannot make any addition to the existing natural resources. For example, improved technology cannot produce an unlimited flow of those vital natural resources that are the raw material for sustained agricultural production.
(vii) How can sufficient food supply be made possible for the future generation?
Ans. Sufficient food supply can be made possible for the future generation by;
(i) Managing and protecting natural resources
(ii) Controlling the fast growing population
(viii) What strategies should be adopted for safe future?
Ans. Following strategies should be adopted for safe future;
(i) We should manage and protect natural resources
(ii) We should achieve optimum world population that is less than two billion.
