RBSE Class 11 Economics Chapter 22 Long Answer Type Questions

Question 1.
Write the functions of environment.
Answer:
Environment performs four main functions of life :

  1. Firstly, it provides the necessary biotic, physical, and chemical systems for the existence of life. This includes atmosphere, rivers, fertile soil, animal and plant kingdom etc. Depletion of ozone layer, greenhouse effect, air pollution, water pollution and decreasing soil fertility is affecting the conditions of life very badly.
  2. Secondly, Environment provides input for production and economic activities. Natural resources can be of two types: renewable and non-renewable. Renewable natural resources can be obtained again. Their excessive exploitation can eliminate them completely. There is a limited reserve of non-renewable natural resources. We should use them sensibly because they can be eliminated due to their excessive exploitation.
  3. Thirdly, absorption functions: Waste material produce by production activities and human activities are absorbed by the Environment in itself. But this capacity of environment is limited. Absorption of long living radioactive materials and heavy elements takes a very long time and thus their waste management should be done very carefully.
  4. Fourthly, providing other services like Natural beauty. These are not essential for existence of life, but they do affect the quality of life.

Question 2.
Discuss the forms, causes and consequences of air pollution.
Answer:
Meaning of Air pollution :
Air pollution refers to the release of pollutants into the air that are detrimental to human health and the planet as a whole. Air pollution occurs when harmful or excessive quantities of substances including gases, particulates, and biological molecules are introduced into Earth’s atmosphere.

Cause of Air pollution :
The effluent gases produced by thermal power plants, industrial units and motorized vehicles get highly concentrated in certain areas. These gases include carbon dioxide, carbon monoxide, sulphur dioxide etc. which are emitted. The rapidly increasing number of motorized vehicles, failures of industrial units to employ appropriate pollution control systems and a major share of thermal power in energy is further intensifying this problem. Motorized vehicles have the maximum contribution in this.

Conclusion :
Due to increase in air pollution, acid rain is caused. Gases emitted from industrial production, i.e. sulphur dioxide, nitric dioxide and carbon dioxide enter the atmosphere and form sulphuric acid, nitric acid and carbolic acid, which fall on earth along with rain. These then coming down to earth with rain, pollute the water sources of the earth and thus affect plant and animal life adversely, buildings are harmed and soil fertility is reduced. That is why, it is needed to control the increasing acidity of the environment by limiting the emission of such gases.

Question 3.
Explain the types of pollution.
Answer:
Following are the types of pollution :

  • Air pollution :
    Air pollution occurs when harmful or excessive quantities of substances including gases, particulates, and biological molecules are introduced into the Earth’s atmosphere. Carbon dioxide is the main air pollutant. Due to increase in air pollution, acid rain is caused. Gas emitted from industrial pollution, i.e. sulphur dioxide, nitric dioxide and carbon dioxide enter the atmosphere, and form sulphuric acid, nitric acid and carbolic acid, which fall on earth along with rain.
  • Water Pollution :
    Activities taking place in the environment which cause deterioration of properties of clean water and reduce the supply of clean water are called water pollution. Water is being polluted by mixing of industrial waste materials in sources Of clean water, dissolution of agricultural chemicals with decomposition in clean water resources, lack of proper solid waste disposal system and dissolution of radioactive materials in water.
  • Soil pollution :
    The upper thin layer of the soil on the earth’s surface is precious for life. Any adverse physical, chemical and biological alteration in it is called soil pollution.
  • Loss of Bio-diversity :
    Bio-diversity is a vital resource of the earth. Every creature has a specific genetic structure, which is an important natural resource. Various types of plants, living beings and micro organisms are the basis of bio-diversity.
  • Solid waste management :
    Materials lying in an improper manner and at inappropriate places, which could be used again, but which obstruct the working system of the environment, are called solid waste. The leftover materials from production of nuclear energy are included in nuclear waste.
  • Noise pollution :
    Unusual and loud sound is called noise. The intensity of sound is measured in decibels. The sound produced in a normal conversation has the intensity of 40-60 decibels. Loud sound is also harmful for human health. Sound pollution can be controlled by making up various norms and laws, by making changes in the technology and by making changes in the human nature.

Question 4.
What are the causes of environmental pollution?
Answer:
Causes of environmental pollution are :

  1. Rapidly increasing industries and failure of industrial units to employ pollution control systems.
  2. Destruction of forest areas, and accordingly, lack of tree plantation and excessive animal grazing.
  3. The amount of carbon emission is increasing due to increase in number of vehicles and their increasing emissions.
  4. Increasing use of chemical fertilizers and insecticides, inappropriate system of irrigation and lack of proper disposal of agricultural wastes.
  5. Growing population- The pressure of population on natural resource is increasing 17 per cent of the population in India lives on 2.17 per cent of global area.
  6. Due to poverty, dependence on conventional sources of energy.
  7. Lack of proper solid waste management system.
  8. Dependence on thermal power plants for energy.
  9. Excessive exploitation of non-renewable natural resources and less regeneration of renewable natural resources.
  10. Not thinking about the environmental threats of loss of bio diversity.
  11. Lack of commitment on the part of developed countries in controlling carbon emission.

Question 5.
Give suggestions for controlling environmental pollution.
Answer:
Suggestions for controlling environmental pollution are :

  1. Pollution should be controlled by adopting appropriate pollution control systems, efficient fuel use and suitable solid waste management systems.
  2. Increasing forest area by tree plantation, control on excessive grazing, adopting social forestry programme to increase forest area.
  3. Developing an adequate public transport system.
  4. Using bio-fertilizers and bio-pesticides in place of chemical fertilizers and pesticides in cultivation and employing efficient system of irrigation.
  5. Population control, so that the burden of population on limited resources can be reduced.
  6. Including concerns of environmental conservation in planning of poverty alleviation programmes.
  7. Proper disposal of industrial and nuclear waste.
  8. Expansion of efficient energy systems and increasing dependence on clean sources of energy like wind energy, solar energy, tidal energy etc.
  9. Searching for alternatives to non-renewable natural resources and sufficient regeneration of renewable resources.
  10. Developed countries should be committed to carbon emission control and transfer clean and sufficient technology for developing countries.

Question 6.
What is meant by sustainable development? Why is it necessary?
Answer:
Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
Need of Sustainable development :
Economic activities bear an effect on environment. Therefore the protection of environment is necessary along with the fulfillment of the needs of the present population. Economic activities should be in harmony with the environment. The utilization of renewable resources should be done without reducing their previous levels. As the use of trees should be done with tree plantation. The utilization of non-renewable resources should not be more than the equivalent quantity of alternative means. The burden of population should be in conformity to the availability of natural capital. Excessive population will have an adverse effect on our capability to fulfill the need of future generations.

The environment friendly sources of energy should be used, like wind energy, solar energy, gobar gas, and mini hydel plants and their development should be done rapidly because on one hand, the production of electricity from coal and petrol is decreasing their stable stock, and on the other hand, it is a cause of pollution. These poisonous materials enter our food through agricultural products and water.
