🟩 Short Answer Questions (1–2 Marks) | Class 12 Green Skills

Q1. What are greenhouse gases? Give examples.
👉 Greenhouse gases are released from burning fossil fuels, vehicles, refrigerants and agriculture. These gases trap heat in the earth atmosphere, stop it from escaping into outer space and cause the earth to heat, leading to ‘global warming’.
👉 Examples: Carbon dioxide, Methane, Nitrous oxide, Ozone, Chlorofluorocarbons (CFCs)

Q2. How do green jobs help in reducing greenhouse gas emissions?
👉 Green jobs matter because they help reduce greenhouse gases by using cleaner options instead of fossil fuels. They promote energy sources like CNG that cause much less pollution.

Q3. What is waste exchange?
👉 This is an approach where the waste from one process is used as the raw material for another. It helps reduce waste disposal by encouraging re-use.

Q4. What is e-waste? Give two examples.
👉 E-waste refers to electronic items which are discarded and are no longer in use. For example – old mobile phones, laptops, televisions and computers.

Q5. What is an ecosystem?
👉 An ecosystem is a community of living and non-living things interacting and supporting each other. This is perfect balance that allows all species to survive and maintain natural stability.

Q6. How does deforestation affect ecosystems?
👉 Deforestation can damage and destroy the ecosystem, leading to climate change and increasing the chances of natural disasters. Such activities severely affect the environment, making survival difficult for living beings.

Q7. How can ecosystems be protected and restored?
👉 Ecosystems can be protected and restored by:
🔆 Planting more trees
🔆 Increasing vegetation
🔆 Investing in soil health
🔆 Avoid cutting of forest
🔆 Controlling greenhouse gas emission

Q8. What does adapting to climate change mean?
👉 Adapting to climate change means finding new ways to survive changes in climate conditions. For example, if there is weather forecast of less rain, farmers will need to grow crops that can survive in drought conditions.

Q9. What is NAPCC and when was it launched? Name any four missions under NAPCC.
👉 NAPCC stands for National Action Plan on Climate Change. It was launched in June 2008 to deal with climate change and related issues. The NAPCC comprises eight missions in specific areas to tackle and adapt to climate change.
These missions are:
1. Solar Energy
2. Enhanced Energy Efficiency
3. Sustainable Habitat
4. Water Mission
5. Sustaining the Himalayan Ecosystem
6. Forestry Mission
7. Sustainable Agriculture
8. Strategic Knowledge for Climate Change

Class 12 Green Skills Important Questions and Answers

🟦 Long Answer Questions (3–5 Marks) | Class 12 Green Skills

Q1. Explain how green jobs help in minimising waste and pollution.
➡️ Promote proper waste collection and segregation
➡️ Support recycling processes (e-waste, plastics, metals)
➡️ Reduce waste generation through waste auditing and control
➡️ Encourage reuse and waste exchange
➡️ Ensure safe transportation and disposal of waste

Q2. Describe the importance of protecting and restoring ecosystems.
👉 Protecting and restoring ecosystems is essential for maintaining the balance of nature and ensuring the survival of all living beings.
👉 Its importance can be explained as follows:
➡️ Maintains natural balance between living and non-living things.
➡️ Prevents and reduces climate change and natural disasters by protecting ecosystem stability.
➡️ Conserves natural resources like clean air, water, fertile soil and biodiversity.
➡️ Provides natural protection against hazards, strengthening the environment’s ability to safeguard itself.
➡️ Reduces greenhouse gas emissions, supporting efforts against global warming.

Q3. What is climate change adaptation? How does NAPCC support it?
👉 Climate change adaptation means finding new ways to survive changes in climate conditions. For example, if there is weather forecast of less rain, farmers will need to grow crops that can survive in drought conditions.
India’s NAPCC (National Action Plan on Climate Change), launched in 2008, introduced eight missions that support adaptation.
👉 These missions are:
1. Solar Energy
2. Enhanced Energy Efficiency
3. Sustainable Habitat
4. Water Mission
5. Sustaining the Himalayan Ecosystem
6. Forestry Mission
7. Sustainable Agriculture
8. Strategic Knowledge for Climate Change

Q4. Identify green jobs in various industries and sectors.
👉 Green Jobs in Different Sectors
➡️ Agriculture: organic farming, pest management, agro-tourism, agro-waste reuse.
➡️ Transportation: EV maintenance, e-rickshaw operation, hybrid/electric vehicle tech.
➡️ Water Conservation: Rainwater harvesting, bamboo drip irrigation, cycle-run pumps, water testing & management.
➡️ Solar & Wind Energy: solar panel installer, solar lighting technician, field/wind farm technician.
➡️ Eco-Tourism: eco-tour guides & operators.
➡️ Building & Construction: construction, landscaping, water management.
➡️ Solid Waste Management: waste collection, segregation, recycling, e-waste management.
➡️ Appropriate Technology: hand/bike-powered pumps, solar lamps, biogas, sanitation, rainwater harvesting, farm mechanisation.

Q5. List some ways by which we can reduce the amount of waste generated.
👉 Following are the ways by which we can reduce the amount of waste generated:
➡️ Reuse scrap material (paper mills, plastics, damaging rolls).
➡️ Ensuring quality control – Reduce waste, decrease in defective products.
➡️ Waste exchange – reducing waste disposal through re-use.
➡️ Manage e-waste (old mobiles, laptops, TVs).
➡️ Use eco-friendly materials (banana leaf plates).

Q6. List some benefits of green jobs.
👉 Benefits of Green Jobs:
➡️ Increase efficient use of energy & raw materials.
➡️ Reduce greenhouse gas emissions.
➡️ Control waste & pollution.
➡️ Protect & restore ecosystems.
➡️ Adapt to climate change.

Green Skills Important Questions Class 12 and Answers

🟨 Competency Based Questions (1-2 Marks)

Q1. A school wants to reduce its use of fossil-fuel–based generators during power cuts. Based on the concept of green jobs and cleaner energy alternatives, suggest one action the school can take and explain how it reduces greenhouse gas emissions.
👉 The school can shift to renewable energy sources like CNG based or Solar power based system. These options release far less pollution than fossil fuels, helping reduce greenhouse gas emissions.

Q2. A paper mill produces a large amount of scrap paper every day. Suggest one waste-minimising practice from the content that can help the mill reduce pollution.
👉 The mill can reuse scrap paper as raw material for another process (waste exchange). This reduces waste disposal and minimises pollution.

Q3. A farmer notices decreasing rainfall in his region. Using the concept of adapting to climate change, recommend one step he can take.
👉 He can grow drought-resistant crops, which help farmers survive changing climatic conditions.

🟧 Case Based Qustions (4-5 Marks)

Case 1:
A city is facing rising temperatures, poor air quality and increasing waste. Many people throw e-waste such as old mobiles and laptops into general garbage. Industries dispose scrap materials without reuse, leading to more pollution. Farmers around the city are struggling because changing weather patterns cause frequent droughts. The government is planning to promote green jobs and implement NAPCC missions to solve these problems.

Q1. Name two major environmental problems faced by the city.
👉 Rising temperatures and poor air quality.

Q2. How can green jobs help manage waste in this city?
👉 Green jobs promote reuse of scrap materials, waste exchange and proper e-waste recycling to reduce pollution.

Q3. What advice should be given to manage e-waste safely?
👉 E-waste should be sent to authorised recycling centres instead of being mixed with household garbage.

Q4. How can farmers adapt to the changing climate?
👉 Farmers can grow drought-resistant crops that survive dry and extreme weather conditions.

Q5. Which NAPCC missions can help in this situation? Name any two.
👉 Solar Energy Mission and Water Mission can help address rising temperatures and water scarcity.
