Man and Climate This video is about the “Man and Climate” academic class of Class 9 – 10 English. The lesson consists of Class 9 10 SSC, English 1st Paper, Unit 5, Lesson 3. This class is useful for students who are preparing for the SSC exam.

 

Man and Climate

 

A. Discuss the questions in pairs.

1. Can man influence the climate? If the answer is yes, explain how.
2. Which human activities are responsible for increasing carbon dioxide in the atmosphere?
3. How can trees help save our environment?

 

 

Now read the text below and find answers to the above questions.

Humans can neither change the sun’s radiation nor the earth’s orbit around the sun. But they can control the increase in the amount of greenhouse gases and their effect on the atmosphere. Only during the last hundred years, the carbon dioxide concentration has been raised alarmingly in the atmosphere and we humans can be held responsible for this.

The main cause of the increase in carbon dioxide levels in the atmosphere is the burning of fossil fuels. Since the end of the 19th century, industrial activities increased rapidly giving rise to many factories. These factories required energy, which was produced through the combustion of coal. Besides coal, other sources of energy such as mineral oil and natural gas were also burned to heat our houses, run cars and airplanes, or produce electricity. Nowadays, about 85 million barrels of crude oil are burned daily.

 

 

 

Every time a fossil raw material is burned, it releases carbon dioxide into the air. Therefore, it is clear that more and more greenhouse gases like carbon dioxide are being generated worldwide by humans. Moreover, we are also strengthening the greenhouse effect by deforestation, which means cutting down trees. Every year enormous areas of forests are destroyed by people to obtain wood and to clear regions for mining and to create pasture. This loss of the forest causes dual problems.

Trees that are burned up release large volumes of carbon dioxide gas into the air. On the other hand, as forests absorb a lot of carbon dioxide from the air and deliver oxygen instead, we also destroy an important storehouse of carbon dioxide when we clear forests.

 

B. Read the statements below and say if they are True/False. If false, give the correct information.
1. Fossil fuels are burned at an alarming rate due to industrialization.
2. Coal is the only fuel used for generating energy.
3. At present, nearly 85 million barrels of crude oil are used weekly.
4. Deforestation is caused by nature.
5. Forests help consume carbon dioxide gases from the air.

 

C. Match the meanings in column B and the words/phrases in column A.

 

D. Write a letter to the Editor of a newspaper expressing your concern about growing deforestation in your area. Describe how deforestation is changing your environment. Also suggest what actions could be taken to stop cutting down trees. Follow the clues below.

• dangers caused by deforestation
• increase of carbon dioxide in the atmosphere
• the greenhouse effect
• making people aware of the adverse effects of deforestation
• making an action plan to stop deforestation

Putting Our Fish In Hot Water is part of Lesson 4, of Unit 5 of SSC English 1st Paper. This book is a lesson of English Today of SSC. That means “Putting Our Fish in Hot Water” is useful for students of Class 9 and Class 10. The lesson describes – The fish population is in serious danger from global warming.

 

Putting Our Fish In Hot Water

 

A. Spend one minute thinking about your life as a fish. In pairs, talk to another “fish” about your life as a fish,

 

B. Do you agree with the following statements on fish and fishing? Discuss with your partner(s).
a. Fish will never disappear. There will always be enough fish to feed the world.
b. In many ways, people are like fish.

 

 

C. The hobby of fishing should be banned to help protect the fish population. Read the text below and say if the statements that follow are True/ C False. If false, give the correct information.

The fish population is in serious danger from global warming. Climate change is increasing the water temperature in rivers, lakes, and seas. This means there is less food and oxygen available for fish. It also means the fish may not grow fully and may have fewer fish fries. Some fishes will become extinct if temperatures rise even by one or two degrees Celsius.
Climate change increases the pressure on the fish population.

Fishes are one of the world’s most valuable biological assets. Forty percent of people in the world eat fish as their main source of protein. If we fail to reduce greenhouse gas emissions, we will increase the pressure on fish. As a result, people who depend on fish will suffer from hunger and poverty.

 

 

Statements:
1. Global warming will kill all the fish within ten years.
2. Some fishes can not reproduce if the water is too warm.
3. A two-degree Celsius rise in temperature will make some species extinct.

4. Fishes are valuable economic investments.

5. Nearly 14% of people depend on fish for their basic food needs.

6. People will suffer a lot if greater pressure is put on fish.

 

D. Role play: Student A is a fish. Student B is a fisherman. First, write a dialogue between the two. Then act it out. Change roles and repeat the role-play

 

E. You are a nature lover. Write a letter to the organizers of the National Climate Change Conference in Bangladesh. Tell them about how global warming is changing your environment. Also, suggest what they can do to help save the fish population.

Environmental Pollution – Dakhil SSC Class 9 10, English 1st Paper, Unit 5, Lesson 2- Environmental Pollution. This class is about “Environmental Pollution”. This class is part of Class 9 10 SSC, English 1st Paper, Unit 5, Lesson 2.

 

Environmental Pollution

 

Now read the following passage to know more about environmental pollution in Bangladesh.

Bangladesh is now in die grip of all sorts of pollution like air pollution, soil pollution, and water pollution. The dwellers of the urban areas are the worst sufferers of such pollution. The indiscriminate industrialization process in Bangladesh over the past decades has created significant environmental problems. We will now read about some of the most common types of environmental pollution and ways of coping with them.

 

 

Air pollution

Air pollution comes from a wide variety of sources. In Bangladesh, poisonous exhausts from industrial plants, brick kilns, old or poorly serviced vehicles, and dust from roads and construction sites are some of the major sources of air pollution. We can minimize this type of pollution by making less use of motor vehicles and avoiding the use of vehicles older than 20 years.

We may also use proper lubricants to lessen the level of emissions and pollutants. We can encourage people to use Compressed Natural Gas (CNG) or Liquid Petroleum Gas (LPG) for fueling their cars. The government may relocate hazardous industries like brick kilns to areas away from human habitation.

 

Water pollution

Water pollution can occur in oceans, rivers, lakes, ponds and underground reservoirs. As different water sources flow together, the pollution can spread easily and quickly. Causes of water pollution include:

• increased sediment from soil
• erosion
• improper waste disposal and littering
• leakage of soil pollution into water supplies
• organic materials that decay in water supplies

In fact, polluting the land means polluting the water. Throwing away a toxic substance on the ground near a water source means it eventually reaches the body of water. As a result, the water is polluted. Industrial wastes must not be disposed of in rivers or lakes. We need to be more careful about disposing of household wastes too.

Use of pesticides means that when it rains, chemicals used in the lawn or garden wash into the water bodies. Therefore, we must be aware of the dangers of using pesticides as they may pollute our rivers, canals, and lakes.

 

 

Soil pollution

Among the most significant causes of soil pollution is the enormous volume of industrial waste which is being produced every day but not disposed of properly. The mismanagement of household wastes, particularly polythene shopping bags, has caused a serious threat to the soil and the drainage system. Another cause of soil pollution is the use of agricultural pesticides, fertilizers, etc. Sometimes fuel leakages from automobiles may get washed away by rain and seep into the nearby soil.

Pesticides and fertilizers are useful for plant growth but their overuse has led to soil pollution. Natural fertilizers and compost can be used instead of their chemical alternatives. Recycling is another way to reduce and control soil pollution. Recycling papers, plastics, and other materials reduce the volume of refuse in landfills. Deforestation also causes erosion, pollution and the loss of fertility in the topsoil. Planting trees and reforestation help prevent soil erosion and pollution.
