Question 25.Give Short answers:
What do you mean by development?
Answer:Development is a comprehensive term which includes an increase in real per capita income, an improvement in the living standard of people, reduction in poverty, illiteracy, etc.
The main features of development are the following:
It is a broader term than economic growth.
It also implies an increase in the production of goods and services in an economy along with the advancement of technology.
It is a long-term process.
It is more suitable to the developing countries.
Both qualitative and quantitative changes are included in it.
It is a result of continuous planned and goal-oriented activities.
There are two bases to check economic development- National income and per capita income.
Question 26.Give Short answers:
What are the indicators of development?
Answer:Development refers to the all-round growth of a country in terms of its economic, social and political wellbeing. There are many indicators of economic development. Such as:
Human development index: HDI was introduced by the UNDP- United Nations Development Program to estimate economic development in terms of education, health, and per capita income.
Life expectancy: It is affected by many factors such as the stability of food supply, political situation, the chances of natural diseases.
Adult literacy: It includes all the people above the age of 15 who are able to read and write.
Gross domestic product per capita: This is the most common indicator for development calculations. It is estimated by dividing the Gross Domestic Product in a year by its population.
Some countries also use other indexes such as the happiness index, corruption index, carbon dioxide emissions, military expenditure etc.
Question 27.Give Short answers:
Why NNP is not considered as a useful measure to compare a country’s development with other countries?
Answer:Gross Domestic Product or GDP is the value of all the final goods and services produced in a country during one year. Net National product or NNP is the GDP plus the Net factor income from abroad or NFIA minus the depreciation (fall in the value of goods and services over time). NNP is not considered as a useful measure to compare a country’s development with other countries because of the following reasons:
NNP accounts for using depreciation but the value of depreciation is different in different economies.
NNP= GDP+NFIA-depreciation. If we assume NFIA to be constant, the NNP can change due to a change in GDP or depreciation. But it is difficult to assess whether the GDP is increasing, or depreciation is rising or decreasing.
India receives a large number of remittances as compared to other countries. This makes NNP an unfavourable measure to calculate development.
NNP has a more complex calculation system.
It is due to these reasons that NNP is not considered a useful measure to compare different country’s development.
Question 28.Give Short answers:
Why human resources are considered the foremost resource of any country?
Answer:Human resources are the collective abilities of the people of a country. They are considered the foremost resource of a country because of the following reasons:
a) every country has certain natural resources such as coal and oil. It also has access to certain renewable resources like solar and wind energy. However, the use of any resource can be done only with the skills and abilities of the humans.
b) any resources can be developed or any technology can be innovated only by the human resources.
c) any organization or company can only develop by incorporating the skills, technology, and abilities of the humans.
Thus, it is extremely important for a country to invest an adequate amount of efforts in developing human resources.
Question 29.Give Short answers:
Expand the following:1. PPP 2. HDI
Answer:PPP- Purchasing power parity is the ratio of purchasing power of the currencies of two trading countries. It is the ratio of the level of price in different nations. So, we can say that the exchange rate between the two countries is equal to the ratio of the price level in the two countries. It can be denoted as
RATE OF EXCHANGE = P1/P2,
where P1 is the price level in country 1, and
P2 is the price level in country 2.
HDI - HDI is the human development index. Human development index was a composite index given by UNDP-United Nations Development Program to measure the progress of a nation in terms of its education, income and health levels. It had three indicators for the same. :
(i) Longevity: It denotes a long and healthy life which is measured by ‘life expectancy at birth’. It indicates how long a newborn baby is expected to live.
(ii) Knowledge: It refers to the literacy rate. It is measured by the percentage of educational attainment, a combined gross enrolment ratio in primary, secondary and tertiary level.
(iii) A decent standard of living: It denotes the standard of life. It is measured by per capita income.
The rank of a country is obtained by the overall achievement in these three basic indicators of human development.
It is an extremely good measure because it is a comprehensive index that covers all the major aspects of life and is used to measure the economic development of a nation.
Question 30.Give Short answers:
Expand the following: 1. NNP 2. PCI
Answer:NNP: NNP is the Net National Product. It can be either at factor cost or market price.
NNP at FC is the sum total of factor incomes earned by the normal residents of a country during one year. Factor income s the income earned by a factor of production for rendering their services to the production.
NNP at MP is the market value of all the final goods and services produced during one year including NFIA and excluding depreciation.
NNP is not considered as a useful measure to compare a country’s development with other countries because it is a complex process and not easy to calculate. Moreover, every country has its own level of NFIA and depreciation which may be different due to many reasons. For example, India has a high level of remittance received (NFIA) as compared to other countries. So, this becomes an unbiased factor to estimate and measure the economic progress between different countries.
PCI- Per capita income. Per capita income is the average income of the country. It is calculated by dividing the national income of a country by its total population. It is used to compare the income level of different countries. It uses only the economic aspect of a nation and ignores other social aspects such as the education level and the health status of the country. So, PCI can be regarded as a single indicator of the economic development of a country. The World Bank has divided the countries into rich and poor, on the basis of their PCI.
Question 31.Give Short answers:
What is ‘Solar Power’?
Answer:Solar power is the power generated from the sun’s heat. The sun emits a lot of heat which can be exploited for economic gains. The humans have successfully developed technologies which can use this heat to generate power. Although the maximum heat of the sun is absorbed by the atmosphere, still the amount received by the Earth is enough to generate power. This heat is used by photovoltaic cells or solar panels.
The amount of solar energy received by the world was calculated to be 3000-50000 exajoules (EJ) which is much larger than the total world energy consumption of 600 EJ, so it can be used widely.
Solar power is a renewable form of energy. This means that a lot of energy can be used, and this can be replenished on its own. It does not cause any pollution and is also not harmful to any living beings.
There are 2 technologies where solar power is used:
Solar cooker: It is a device which uses the sun’s energy to cook food. The basic underlying principle is that the black surface absorbs more heat and the glass plate used produces the greenhouse effect inside the cooker.
Solar panel: It is a device made of silicon which converts the energy into electricity. It is used in artificial satellites, space probes, traffic signals, radio, wireless technology etc.
There are many advantages to using this form of energy such as it is a renewable form of energy and is environment-friendly. It is also very easy to install and use. However, one major disadvantage is that it cannot be used on cloudy or rainy days.
Question 32.Answer in detail:
Discuss the policies for sustainable development.
Answer:Sustainable development is the process of economic development where the resources are used in a judicious manner to satisfy the needs of the present generation as well as to conserve them for future generation.
According to the United Nations Conference on Environment and Development (UNCED), sustainable development can be defined as “development strategy that meets the need of present generation without compromising the ability of future generation to meet their own needs.”
According to Edward Barbier 'Sustainable development is one which is directly concerned with increasing the material standards of living of the poor at the grass root level.'
The features of sustainable development are:
a) judicious use of natural resources
b) no reduction in resources for future generation
c) a proper check on the pollution level
d) a rise in the per capita income and economic welfare
The policies for sustainable development are:
a) sustainable development can greatly succeed if the country relies on nonconventional methods of energy. Nonconventional energy is the one which can be replenished in no time. They are pollution free and do not cause any type of harm to the living beings of the planet. Solar energy, wind energy, and hydroelectricity are a few examples of nonconventional energy forms.
b) the use of compressed natural gas or CNG in public transport system as fuel can help to decrease the air pollution.
c) to increase the level of production the farmers can use organic fertilizers for production. In some areas, cattle are used because their waste production is extremely useful in the form of fertilizers. Earthworms can convert organic matter into compost faster than the normal process of composting.
d) with green revolution pan to use the chemical pesticides to produce more. Certain negative impacts on soil milk and fishes. To overcome this problem pesticides should be used which are based on plants like the name even animals like snake and Peacock can help to control the pest
Thus, implementing the above policies can help to promote a sustainable form of development.
Question 33.Answer in detail:
Describe in detail about environmental policies in India.
Answer:According to the Environment Act-1986, ‘Environment includes, water, air and land and the interrelationship which exists among and between water, air, land, and human beings and other creatures, plants, microorganisms, and property’.
The major threat to the environment of India is poverty, population, and increasing development in the industrial sector. Pollution of air, water pollution, land degradation etc is other major concerns of India. The development activities in India have led to such disastrous situation of the environment.
For the first time, the importance of promoting and preserving the environment along with development was introduced in the fourth five-year plan. However, it was only in the upcoming plans that the ideas expressed in this plan were made into concrete programs.
The fifth five-year plan laid great stress on the need of a national committee which would work in coordination with development. All the major industrial decisions where implemented only after carefully analyzing its impact on the environment. A huge emphasis was laid on the fact that the development should not cause any reduction in the quality of life. The link between development and environment was heavily stressed.
In the sixth five-year plan chapter called environment and development was included which focused on agriculture, forestry, mineral, fishery, water, marine management, renewable sources of energy and human settlement.
The Government of India set up a committee in January 1980 under the Chairmanship of Shri. N.D. Tiwari, then Deputy Chairman of the Planning Commission to review the existing environmental laws and to recommend measures for Environment protection. It emphasized the need of a system for the protection of the countries natural resources such as Land, water and air to conserve the countries ecological system.
The Government of India also introduced certain other policies such as The National Conservation Strategy and Policy Statement on Environment and Development 1992, The National Forest Policy, 1988 and the Policy Statement for Abatement of Pollution, 1992. They all focused on matters relating to environmental management at a national level. In 2006 the national environment Policy was approved by the Union Cabinet. It was a comprehensive National environment policy that brought together the guiding principles of all the above documents.
The objectives of national environment policy 2006 are:
a) the conservation of critical environmental resources which are important for human life, livelihood, and economic growth.
b) intergenerational equity to meet the needs of the future generation as well
c) integration of the environmental policies with the overall development of the country
d) ensure efficient use of all the environment resources
e) to apply the principles of good governance such as transparency, rationality oma accountability and reduction in time to the regulation of
Question 34.Answer in detail:

Answer:The natural resources are divided into two categories- renewable resources and nonrenewable resources. The difference between the two is given in the table below
Question 35.Answer in detail:
Mention any five environmental acts and their action.
Answer:The Government of India has introduced many acts for the preservation and promotion of the environment of a country. A few of them are mentioned below:
a) The Wildlife Protection Act, 1972: It was introduced with the aim of protecting the wildlife of the country, control poaching, smuggling and illegal trade in wildlife. It was amended in 2003 and the punishment of any offence under this act was made stricter. The main objective is to provide protection to the listed endangered plants and animals and ecologically important areas.
b) The Water (Prevention and Control of Pollution) Act, 1974: This was introduced to provide prevention and control of water pollution in the country. It has set up different boards for the prevention and maintenance of water level in the country. This act prohibits the discharge of a pollutant into any waterbody beyond a given standard. It can also punish for noncompliance of any rule. At the centre, CPCB has been set up and at the state level, SPCB has been functioning.
b) The forest conservation act 1980: It was introduced to help conserve the forest of India. It restricts and regulates the use of forest land for nonforest purpose without obtaining prior approval from the central government. It lays down certain prerequisite for the diversion of forest land for any nonforest purpose. The Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006, recognizes the right of the scheduled tribes and other traditional forest dwellers over the forest area in Habitat by them.
d) The Air (Prevention and Control of Pollution) Act, 1981: This act was introduced to prevent, the air pollution as well the establishment of boards at both send for implementing an air quality standard was established under this act. The use of polluting fuels and other related substances were prohibited. The state government has the power to declare any area within the state as air pollution control area. Any industrial plant has to obtain consent from the state government before operating.
c) The Biological Diversity Act, 2002: The main purpose of the act is to conserve the biological resources and use them in a sustainable manner. National biodiversity authority in Chennai has been established to implement the objects of this act
Question 36.Projects and Activities:
List the various ways in which the problems of garbage and emissions are being dealt with around the world.
Answer:The measures that have been taken to solve the issue of garbage and emissions are:
1. Waste reduction and reuse: Remedial measures like reduction and reuse of waste are taken. Reduction of waste means encouraging the Producers and Consumers to produce less waste such as reduction in packing, using bags and covers made of cloth or recycled material. Reusing of waste means encouraging the public to purchase reusable goods. They are also advised to donate old clothes, utensils etc to the needy.
2. Recycle waste: Recycling means reducing the amount of waste and using the waste generated for some other purpose. There are 3 levels of recycling process:
i. Reconstructing the recyclable material and metal from stored waste and collecting them separately,
ii. Preparation of raw material from collected metal.
iii. Creating a new product from raw material.
3. Collection of waste: The local bodies appoint a staff which has the responsibility to collect the waste and recycled waste twice a week. But the waste that is a shelter to the flies or spreading odour has to be collected immediately.
4. Treatment and disposal: The new garbage treatment technology has discovered that if the management form is changed, it can help to reduce the amount of waste generated, which would imply a simpler waste disposal method. The waste is disposed on the basis of the amount of waste and type.
5. Incineration: In this method, the waste is combusted in the presence of oxygen. After accumulation, the garbage turns into carbon dioxide and water vapour. This method helps to reduce transport cost and the production of methane.
6. Gasification and pyrolysis: Both are similar thermal methods. In this method the component of the waste is dissolved at high temperature these are used in low oxygen or nonoxygen field.
7) Solid waste management: Solid waste management means to manage the process of treatment, salvage, reuse, re-rotation change of energy without affecting the environment and the public health in this system the state has the responsibility to provide training, suggestion, and resources to the local bodies of Urban and rural areas for solid waste management. In this system cleaning workers are employed on a regular or contractual basis to bring garbage from the houses hospitals and other establishment and gather it at the garbage collection centre. From this centre, it is taken to the garbage disposal centre through different means of transportation like trucks, tractors etc. At the disposal centre, the garbage is divided into different categories and then disposed of accordingly.
Question 37.HOTS
Write in detail what kind of environmental problems you face in your locality.
Answer:Our environment is constantly changing. The need to be aware of our environment is now more than ever. The climate changes, global warming, increasing pollution levels have created a hazardous situation for humans. There are many environmental problems that we face all around us. The most dangerous ones are those that we face in our own locality. A few of them are mentioned below:
a) Waste disposal: It is said that n average person disposes of 4.6 pounds of trash per day. Sadly, most of the people tend to throw waste on the road or on the empty plots. Despite, proper trash cans set up everywhere and the arrangement of a sweeper who can collect the trash from your doorstep, people tend to dispose of waste in the wrong places.
b) Water scarcity: People have taken water for granted. The continuous waste of water in the household and building maintenance have created a serious issue of water scarcity.
c) Urban Sprawl: With more and more people shifting to urban areas, the housing problems have been on the rise. Any small empty plot is converted into a multi-story apartment. This has made the locality very congested and increased the traffic issues.
d) Diseases: The diseases have been on a continuous rise due to water logging and inappropriate waste disposal. The children are being affected by it the most.

Per Capita Income or PCI = National income of a country/ Total population of the country.
For example, the national income of country X is Rs, 5,00,000 and its total population is 5000.
So, PCI = 5,00,000/5,000
PCI = 100
It is used to compare the income level of different countries. It uses only the economic aspect of a nation and ignores other social aspects such as the education level and the health status of the country. So, PCI can be regarded as a single indicator of the economic development of a country.
The World Bank has divided the countries into rich and poor, on the basis of their PCI.

What are the indicators of development?
Answer:
Development refers to the all-round growth of a country in terms of its economic, social and political wellbeing. There are many indicators of economic development. Such as:
Human development index: HDI was introduced by the UNDP- United Nations Development Program to estimate economic development in terms of education, health, and per capita income.
Life expectancy: It is affected by many factors such as the stability of food supply, political situation, the chances of natural diseases.
Adult literacy: It includes all the people above the age of 15 who are able to read and write.
Gross domestic product per capita: This is the most common indicator for development calculations. It is estimated by dividing the Gross Domestic Product in a year by its population.
Some countries also use other indexes such as the happiness index, corruption index, carbon dioxide emissions, military expenditure etc.
Question 27.
Give Short answers:
Why NNP is not considered as a useful measure to compare a country’s development with other countries?
Answer:
Gross Domestic Product or GDP is the value of all the final goods and services produced in a country during one year. Net National product or NNP is the GDP plus the Net factor income from abroad or NFIA minus the depreciation (fall in the value of goods and services over time). NNP is not considered as a useful measure to compare a country’s development with other countries because of the following reasons:
NNP accounts for using depreciation but the value of depreciation is different in different economies.
NNP= GDP+NFIA-depreciation. If we assume NFIA to be constant, the NNP can change due to a change in GDP or depreciation. But it is difficult to assess whether the GDP is increasing, or depreciation is rising or decreasing.
India receives a large number of remittances as compared to other countries. This makes NNP an unfavourable measure to calculate development.
NNP has a more complex calculation system.
It is due to these reasons that NNP is not considered a useful measure to compare different country’s development.

b) any resources can be developed or any technology can be innovated only by the human resources.
c) any organization or company can only develop by incorporating the skills, technology, and abilities of the humans.
Thus, it is extremely important for a country to invest an adequate amount of efforts in developing human resources.
Question 29.
Give Short answers:
Expand the following:1. PPP 2. HDI
Answer:
PPP- Purchasing power parity is the ratio of purchasing power of the currencies of two trading countries. It is the ratio of the level of price in different nations. So, we can say that the exchange rate between the two countries is equal to the ratio of the price level in the two countries. It can be denoted as
RATE OF EXCHANGE = P1/P2,
where P1 is the price level in country 1, and
P2 is the price level in country 2.
HDI - HDI is the human development index. Human development index was a composite index given by UNDP-United Nations Development Program to measure the progress of a nation in terms of its education, income and health levels. It had three indicators for the same. :
(i) Longevity: It denotes a long and healthy life which is measured by ‘life expectancy at birth’. It indicates how long a newborn baby is expected to live.
(ii) Knowledge: It refers to the literacy rate. It is measured by the percentage of educational attainment, a combined gross enrolment ratio in primary, secondary and tertiary level.
(iii) A decent standard of living: It denotes the standard of life. It is measured by per capita income.
The rank of a country is obtained by the overall achievement in these three basic indicators of human development.
It is an extremely good measure because it is a comprehensive index that covers all the major aspects of life and is used to measure the economic development of a nation.
Question 30.
Give Short answers:
Expand the following: 1. NNP 2. PCI
Answer:
NNP: NNP is the Net National Product. It can be either at factor cost or market price.
NNP at FC is the sum total of factor incomes earned by the normal residents of a country during one year. Factor income s the income earned by a factor of production for rendering their services to the production.
NNP at MP is the market value of all the final goods and services produced during one year including NFIA and excluding depreciation.
NNP is not considered as a useful measure to compare a country’s development with other countries because it is a complex process and not easy to calculate. Moreover, every country has its own level of NFIA and depreciation which may be different due to many reasons. For example, India has a high level of remittance received (NFIA) as compared to other countries. So, this becomes an unbiased factor to estimate and measure the economic progress between different countries.
PCI- Per capita income. Per capita income is the average income of the country. It is calculated by dividing the national income of a country by its total population. It is used to compare the income level of different countries. It uses only the economic aspect of a nation and ignores other social aspects such as the education level and the health status of the country. So, PCI can be regarded as a single indicator of the economic development of a country. The World Bank has divided the countries into rich and poor, on the basis of their PCI.
Question 31.
Give Short answers:
What is ‘Solar Power’?
Answer:
Solar power is the power generated from the sun’s heat. The sun emits a lot of heat which can be exploited for economic gains. The humans have successfully developed technologies which can use this heat to generate power. Although the maximum heat of the sun is absorbed by the atmosphere, still the amount received by the Earth is enough to generate power. This heat is used by photovoltaic cells or solar panels.
The amount of solar energy received by the world was calculated to be 3000-50000 exajoules (EJ) which is much larger than the total world energy consumption of 600 EJ, so it can be used widely.
Solar power is a renewable form of energy. This means that a lot of energy can be used, and this can be replenished on its own. It does not cause any pollution and is also not harmful to any living beings.
There are 2 technologies where solar power is used:
Solar cooker: It is a device which uses the sun’s energy to cook food. The basic underlying principle is that the black surface absorbs more heat and the glass plate used produces the greenhouse effect inside the cooker.
Solar panel: It is a device made of silicon which converts the energy into electricity. It is used in artificial satellites, space probes, traffic signals, radio, wireless technology etc.
There are many advantages to using this form of energy such as it is a renewable form of energy and is environment-friendly. It is also very easy to install and use. However, one major disadvantage is that it cannot be used on cloudy or rainy days.
Question 32.
Answer in detail:
Discuss the policies for sustainable development.
Answer:
Sustainable development is the process of economic development where the resources are used in a judicious manner to satisfy the needs of the present generation as well as to conserve them for future generation.
According to the United Nations Conference on Environment and Development (UNCED), sustainable development can be defined as “development strategy that meets the need of present generation without compromising the ability of future generation to meet their own needs.”
According to Edward Barbier 'Sustainable development is one which is directly concerned with increasing the material standards of living of the poor at the grass root level.'
The features of sustainable development are:
a) judicious use of natural resources
b) no reduction in resources for future generation
c) a proper check on the pollution level
d) a rise in the per capita income and economic welfare
The policies for sustainable development are:
a) sustainable development can greatly succeed if the country relies on nonconventional methods of energy. Nonconventional energy is the one which can be replenished in no time. They are pollution free and do not cause any type of harm to the living beings of the planet. Solar energy, wind energy, and hydroelectricity are a few examples of nonconventional energy forms.
b) the use of compressed natural gas or CNG in public transport system as fuel can help to decrease the air pollution.
c) to increase the level of production the farmers can use organic fertilizers for production. In some areas, cattle are used because their waste production is extremely useful in the form of fertilizers. Earthworms can convert organic matter into compost faster than the normal process of composting.
d) with green revolution pan to use the chemical pesticides to produce more. Certain negative impacts on soil milk and fishes. To overcome this problem pesticides should be used which are based on plants like the name even animals like snake and Peacock can help to control the pest
Thus, implementing the above policies can help to promote a sustainable form of development.

Answer in detail:
Describe in detail about environmental policies in India.
Answer:
According to the Environment Act-1986, ‘Environment includes, water, air and land and the interrelationship which exists among and between water, air, land, and human beings and other creatures, plants, microorganisms, and property’.
The major threat to the environment of India is poverty, population, and increasing development in the industrial sector. Pollution of air, water pollution, land degradation etc is other major concerns of India. The development activities in India have led to such disastrous situation of the environment.
For the first time, the importance of promoting and preserving the environment along with development was introduced in the fourth five-year plan. However, it was only in the upcoming plans that the ideas expressed in this plan were made into concrete programs.
The fifth five-year plan laid great stress on the need of a national committee which would work in coordination with development. All the major industrial decisions where implemented only after carefully analyzing its impact on the environment. A huge emphasis was laid on the fact that the development should not cause any reduction in the quality of life. The link between development and environment was heavily stressed.
In the sixth five-year plan chapter called environment and development was included which focused on agriculture, forestry, mineral, fishery, water, marine management, renewable sources of energy and human settlement.
The Government of India set up a committee in January 1980 under the Chairmanship of Shri. N.D. Tiwari, then Deputy Chairman of the Planning Commission to review the existing environmental laws and to recommend measures for Environment protection. It emphasized the need of a system for the protection of the countries natural resources such as Land, water and air to conserve the countries ecological system.
The Government of India also introduced certain other policies such as The National Conservation Strategy and Policy Statement on Environment and Development 1992, The National Forest Policy, 1988 and the Policy Statement for Abatement of Pollution, 1992. They all focused on matters relating to environmental management at a national level. In 2006 the national environment Policy was approved by the Union Cabinet. It was a comprehensive National environment policy that brought together the guiding principles of all the above documents.
The objectives of national environment policy 2006 are:
a) the conservation of critical environmental resources which are important for human life, livelihood, and economic growth.
b) intergenerational equity to meet the needs of the future generation as well
c) integration of the environmental policies with the overall development of the country
d) ensure efficient use of all the environment resources
e) to apply the principles of good governance such as transparency, rationality oma accountability and reduction in time to the regulation of

Mention any five environmental acts and their action.
Answer:
The Government of India has introduced many acts for the preservation and promotion of the environment of a country. A few of them are mentioned below:
a) The Wildlife Protection Act, 1972: It was introduced with the aim of protecting the wildlife of the country, control poaching, smuggling and illegal trade in wildlife. It was amended in 2003 and the punishment of any offence under this act was made stricter. The main objective is to provide protection to the listed endangered plants and animals and ecologically important areas.
b) The Water (Prevention and Control of Pollution) Act, 1974: This was introduced to provide prevention and control of water pollution in the country. It has set up different boards for the prevention and maintenance of water level in the country. This act prohibits the discharge of a pollutant into any waterbody beyond a given standard. It can also punish for noncompliance of any rule. At the centre, CPCB has been set up and at the state level, SPCB has been functioning.
b) The forest conservation act 1980: It was introduced to help conserve the forest of India. It restricts and regulates the use of forest land for nonforest purpose without obtaining prior approval from the central government. It lays down certain prerequisite for the diversion of forest land for any nonforest purpose. The Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006, recognizes the right of the scheduled tribes and other traditional forest dwellers over the forest area in Habitat by them.
d) The Air (Prevention and Control of Pollution) Act, 1981: This act was introduced to prevent, the air pollution as well the establishment of boards at both send for implementing an air quality standard was established under this act. The use of polluting fuels and other related substances were prohibited. The state government has the power to declare any area within the state as air pollution control area. Any industrial plant has to obtain consent from the state government before operating.
c) The Biological Diversity Act, 2002: The main purpose of the act is to conserve the biological resources and use them in a sustainable manner. National biodiversity authority in Chennai has been established to implement the objects of this act

List the various ways in which the problems of garbage and emissions are being dealt with around the world.
Answer:
The measures that have been taken to solve the issue of garbage and emissions are:
1. Waste reduction and reuse: Remedial measures like reduction and reuse of waste are taken. Reduction of waste means encouraging the Producers and Consumers to produce less waste such as reduction in packing, using bags and covers made of cloth or recycled material. Reusing of waste means encouraging the public to purchase reusable goods. They are also advised to donate old clothes, utensils etc to the needy.
2. Recycle waste: Recycling means reducing the amount of waste and using the waste generated for some other purpose. There are 3 levels of recycling process:
i. Reconstructing the recyclable material and metal from stored waste and collecting them separately,
ii. Preparation of raw material from collected metal.
iii. Creating a new product from raw material.
3. Collection of waste: The local bodies appoint a staff which has the responsibility to collect the waste and recycled waste twice a week. But the waste that is a shelter to the flies or spreading odour has to be collected immediately.
4. Treatment and disposal: The new garbage treatment technology has discovered that if the management form is changed, it can help to reduce the amount of waste generated, which would imply a simpler waste disposal method. The waste is disposed on the basis of the amount of waste and type.
5. Incineration: In this method, the waste is combusted in the presence of oxygen. After accumulation, the garbage turns into carbon dioxide and water vapour. This method helps to reduce transport cost and the production of methane.
6. Gasification and pyrolysis: Both are similar thermal methods. In this method the component of the waste is dissolved at high temperature these are used in low oxygen or nonoxygen field.
7) Solid waste management: Solid waste management means to manage the process of treatment, salvage, reuse, re-rotation change of energy without affecting the environment and the public health in this system the state has the responsibility to provide training, suggestion, and resources to the local bodies of Urban and rural areas for solid waste management. In this system cleaning workers are employed on a regular or contractual basis to bring garbage from the houses hospitals and other establishment and gather it at the garbage collection centre. From this centre, it is taken to the garbage disposal centre through different means of transportation like trucks, tractors etc. At the disposal centre, the garbage is divided into different categories and then disposed of accordingly.

Write in detail what kind of environmental problems you face in your locality.
Answer:
Our environment is constantly changing. The need to be aware of our environment is now more than ever. The climate changes, global warming, increasing pollution levels have created a hazardous situation for humans. There are many environmental problems that we face all around us. The most dangerous ones are those that we face in our own locality. A few of them are mentioned below:
a) Waste disposal: It is said that n average person disposes of 4.6 pounds of trash per day. Sadly, most of the people tend to throw waste on the road or on the empty plots. Despite, proper trash cans set up everywhere and the arrangement of a sweeper who can collect the trash from your doorstep, people tend to dispose of waste in the wrong places.
b) Water scarcity: People have taken water for granted. The continuous waste of water in the household and building maintenance have created a serious issue of water scarcity.
c) Urban Sprawl: With more and more people shifting to urban areas, the housing problems have been on the rise. Any small empty plot is converted into a multi-story apartment. This has made the locality very congested and increased the traffic issues.
d) Diseases: The diseases have been on a continuous rise due to water logging and inappropriate waste disposal. The children are being affected by it the most.

How is the Per Capita income calculated?
Answer:
Per capita income is the average income of the country. It is calculated by dividing the national income of a country by its total population.
The formula for per capita income :
Per Capita Income or PCI = National income of a country/ Total population of the country.
For example, the national income of country X is Rs, 5,00,000 and its total population is 5000.
So, PCI = 5,00,000/5,000
PCI = 100
It is used to compare the income level of different countries. It uses only the economic aspect of a nation and ignores other social aspects such as the education level and the health status of the country. So, PCI can be regarded as a single indicator of the economic development of a country.
The World Bank has divided the countries into rich and poor, on the basis of their PCI.
