Question 1. Discuss the negative effects of the Green Revolution.
Answer:

Negative Effects Of The Green Revolution:-

The negative effects of the Green Revolution are as follows-

1. Loss of soil fertility:

An area of land loses its fertility if it is used to grow the same crops repeatedly year after year, rendering it barren and useless after some time.

2. Increase in salinity:

Repeated cultivation on the same plot of land results in its repeated irrigation, which increases the salinity of the soil, thereby making the soil infertile.

3. Use of chemical fertilizers and pesticides:

The amounts of chemical fertilizers and pesticides being used since the time of the Green Revolution have had adverse effects on the soil. It makes the soil infertile, increase its salinity and pollutes it as well.

4. Loss in biodiversity:

The repeated cultivation of the same high-yielding variety of crops results in the loss of biodiversity.

5. Genetic change:

High-yielding varieties of seeds are usually grown by making genetic modifications of the seeds. These crops, when consumed by human beings or domestic animals, can have adverse effects on their bodies.

Question 2. Give a brief account of environmental degradation in India, citing recent examples.
Answer:

Environmental Degradation In India, Citing Recent Examples:-

India is a fast-developing country. Various activities such as the construction of roads and railways, the building of townships, the extraction of natural resources, industrialization, etc., are taking place in different parts of the country.

Though these activities are necessary for the development of human society, they also have adverse effects on the environment. Examples of environmental degradation due to development are discussed below-

Environmental degradation in India examples

Green Revolution and the Degradation of Land under Cultivation:

The phase in the early 1970s when improved agronomic technology was taken up for farming, in the states of Punjab, Haryana, etc., which resulted in a high yield of crops, is known as the Green Revolution.

But this ‘revolution’ was also responsible for the degradation of land under cultivation and several environmental problems arising from it.

Problems:

Cultivating crops repeatedly on the same patch of land makes it infertile and it slowly turns in to barren and

1. Excessive use of pesticides kills the useful microorganisms present in the soil.
2. Use of chemical fertilizers also changes the nature of the soil and degrades its quality.
3. Excessive irrigation increases the salinity of the soil.
4. Various genetic problems can occur in the crops that are produced from high-yielding seeds.
5. Unregulated use of underground water is lowering the level of the watertable.
6. Farming methods using modern technology are very costly and hence poor farmers face difficulties in using those.

Filling of wetlands and environmental degradation:

Wetlands also play important functions such as controlling floods, maintaining the level of the underground watertable, providing water for irrigation, etc.

However, they are now undergoing detrimental changes, which is further degrading the environment.

Problems:

1. Several wetlands are being filled up for construction purposes. This increases the salinity of the soil as well as decreases the level of the groundwater table.
2. The filling up of wetlands increases the chances of flood in the surrounding areas.
3. Wetlands are often used as landfills, which pollute the air, water, and soil of that place. Dumping of garbage in wetlands has contaminated the groundwater and soil substantially, which has also made the air stink.

Ganga Action Plan:

The 2525 km long river Ganga has become one of the most polluted rivers today due to various causes. The river is especially polluted in the 600 km stretch from the estuary toward its source.

The project that has been taken up to make the Ganga pollution free is known as the Ganga Action Plan (GAP).

Time of initiation and objectives of the Ganga Action Plan:

This project was officially initiated in Varanasi on January 14, 1986. The objectives of the Ganga Action Plan-

1. Make the water of the Ganga pollution-free and maintain the ecological balance;
2. Maintain the depth of the river;
3. Make the river water suitable for drinking;
4. Prevent rapid erosion of river banks;
5. Keep the surrounding areas of the river clean and beautiful.

To attain the above objectives, a huge amount of funds has been allotted. The sewage generated from 25 Class I cities was tackled. Many sewage treatment plants were also established.

Advanced Questions And Answers

Question 1. How can we protect our environment even while carrying on development?
Answer:

We Can Protect Our Environment Even While Carrying On Development:-

Along with carrying on developmental processes, the earth can also be protected and conserved. In order to do this the following steps should be taken-

1. Recycling of substances:

Recycling of used substances enables development as well as helps reduce the wastage of resources.

2. Development of technology:

Both technology and knowledge should be put to use to figure out in how many different ways a single material can be used.

Example- A decade ago, 10 tonnes of coal was required to produce 1 tonne of steel. However, nowadays, the production of 1 tonne of steel requires only 0.75 tonnes of coal.

3. Judicious use of resources:

Instead of wasting resources in an unplanned manner, they should be used judiciously and within a certain limit.

Example- If we use public transport instead of private transport, we can save a lot of fuel.

Question 2. Write a short note on Green Bench.
Answer:

Green Bench:-

A separate bench, called the Green Bench, has been formed for dealing with the issues related to the environment. The Supreme Court of India has ordered the High Courts of different states to form this bench.

West Bengal government formed its Green Bench in the year 1986.

Issues of appeal:

The issues which are handled by this Bench include

1. Filling up of ponds and wetlands,
2. Pollution from the transport sector,
3. Pollution caused by industries,
4. Pollution from waste material and garbage and sound pollution.

Air quality issues in Indian cities

Special advantage: Common people can easily convey their problems to this Bench. An ordinary letter enjoys the status of an appeal in this Bench. This Bench is also known as Environment Court.

Question 3. Briefly discuss about arsenic pollution.
Answer:

Arsenic Pollution:-

When the arsenic level in the drinking water of a particular area rises above the acceptable limit, the water is said to be contaminated by arsenic. Groundwater in different parts of West Bengal contains high levels of arsenic.

Sources of arsenic:

1. Sedimentary rock layers contain arsenic which comes up with groundwater.
2. Excessive use of arsenic-laced pesticides which, in turn, contaminates the environment.
3. The ores of iron, lead as well as coal themselves contain arsenic. So arsenic is released when these ores are melted and when coal is burnt.

Effects:

1. When arsenic comes into contact with human hair, nails, and skin, it gives rise to black spots. This is known as ‘Blackfoot disease.
2. Drinking and using of water that is contaminated with arsenic can affect the lungs, kidneys, and liver very badly. It can even cause cancer.

Question 4. Write a short note on global warming.
Answer:

Global Warming:-

An increase in the number of greenhouse gases in the atmosphere is causing a rise in the average temperature of the earth. This gradual increase of temperature all over the world is known as global warming.

According to Intergovernmental Panel on Climate Change, the temperature of the earth has increased by about 0.74°C in the last century. Besides carbon dioxide, gases such as methane, nitrous oxide, freon, ozone, and water vapor are also responsible for global warming.

Effects:

1. Sea level is rising due to the melting of ice in the polar regions.
2. Coastal areas are getting inundated.
3. Forest fires are occurring and large-scale destruction of forests is an inevitable effect.
4. Various plants and animals are being lost permanently.
5. Different types of diseases will also spread.

Government initiatives for environmental protection in India

Question 5. What is eutrophication?
Answer:

Eutrophication:-

Phosphates present mostly in detergents, fertilisers, etc., reach closed water bodies (ponds, lakes) due to surface run-off from the land. This results in excessive growth of algae in those waterbodies. This process is known as eutrophication.

Harmful effects:

1. The level of oxygen present in water decreases, creating a Biological Oxygen Demand (BOD).
2. Excessive algae create a layer over water, blocking the sunlight to penetrate. This prevents underwater plants from receiving sunlight and they are unable to perform photosynthesis.
3. Layers of algae on the water’s surface obstruct the movement of boats. These also release a toxin, which is harmful for livestock.

WBBSE Class 8 Geography Chapter 8 Question Answer

Chemical disaster:

Lack of skilled laborers, back-dated technology, and carelessness of laborers are the main causes of a chemical disaster. 1984 Bhopal Gas Tragedy, the Nuclear disaster of Chornobyl, 1908, etc., are a few examples of this type of disaster.

Inflation and decreasing balance between demand and supply:

Inflation is an economic problem. Population explosion, trade deficit, all these lead to inflation. These also disrupt the balance between demand and supply.

Depletion of natural resources:

Excessive use of natural resources, forest fires, and animal hunting are slowly depleting the biodiversity from the surface of the earth.

Flood:

Deforestation, unplanned farming, filling of wetlands, and unscientific construction of river dams lead to floods.

Global warming and climate change:

Excessive use of fossil fuels, deforestation, unplanned urbanization, etc., are increasing the average temperature of the earth. This in turn, is causing the polar ice caps to melt, causing a significant rise in the sea level.
