Question 16:
Read the following case study:

A city faced frequent floods due to heavy rainfall. Experts found that excessive construction and lack of trees were the main causes. The government launched a 'Green City' initiative to plant more trees.

Based on the case study, answer the following:
(a) Why did the city face frequent floods?
(b) What was the government's solution to this problem?
(c) How does planting trees help in preventing floods?
Answer:

(a) The city faced frequent floods because:

  • Excessive construction reduced the land's ability to absorb rainwater.
  • The lack of trees meant there were no roots to hold the soil and slow down water flow.

(b) The government's solution was to launch the 'Green City' initiative, which focused on planting more trees to combat the issue.

(c) Planting trees helps prevent floods in the following ways:

  • Tree roots bind the soil, reducing soil erosion and allowing better water absorption.
  • Trees act as natural sponges, soaking up excess rainwater and releasing it slowly.
  • They help maintain the water cycle, ensuring balanced rainfall distribution.

Question 17:
Read the following case study:
In a small village, people heavily depended on cutting trees for firewood and construction. Over time, the forest cover reduced drastically, leading to soil erosion and water scarcity. The villagers realized their mistake and started a tree plantation drive.
Based on the case, answer:
(a) What were the two major consequences of deforestation faced by the villagers?
(b) How did the villagers attempt to rectify their mistake?
Answer:

(a) The two major consequences of deforestation faced by the villagers were soil erosion and water scarcity. Deforestation removed the tree roots that held the soil together, leading to erosion. Additionally, trees play a crucial role in the water cycle, and their absence reduced groundwater recharge, causing water scarcity.

(b) The villagers attempted to rectify their mistake by initiating a tree plantation drive. Planting trees helps restore ecological balance by preventing soil erosion, improving water retention, and providing habitat for wildlife. This effort also promotes sustainable living for future generations.

Question 18:
Read the following scenario:
A city faced severe air pollution due to excessive vehicular emissions and industrial activities. The local government introduced measures like carpooling incentives and stricter emission norms for factories.
Based on the scenario, answer:
(a) Identify two human activities contributing to air pollution in the city.
(b) Explain how the government's measures can help reduce pollution.
Answer:

(a) The two human activities contributing to air pollution in the city were excessive vehicular emissions and industrial activities. Vehicles release harmful gases like carbon monoxide, while factories emit pollutants such as sulfur dioxide.

(b) The government's measures can help reduce pollution in the following ways:

  • Carpooling incentives reduce the number of vehicles on the road, lowering overall emissions.
  • Stricter emission norms ensure factories adopt cleaner technologies, minimizing harmful pollutants released into the air.
These steps promote environmental sustainability and improve public health.

Question 19:
Read the following case study and answer the question below:

Rahul's town has seen rapid urbanization in the past decade, leading to the cutting down of trees to build apartments and roads. The local temperature has risen by 2°C, and air pollution levels have increased. Residents now face health issues like asthma and heat strokes.

How does deforestation, as described in the case, impact the environment and human health? Support your answer with examples from the text.
Answer:

The case study highlights the severe consequences of deforestation due to urbanization. The cutting down of trees has led to:

  • Rise in temperature: The local temperature increased by 2°C because trees naturally cool the environment through transpiration and shade.
  • Increased air pollution: Trees act as natural air filters, absorbing pollutants like CO2. Without them, pollution levels rise, causing respiratory issues like asthma.
  • Health problems: Residents suffer from heat strokes due to higher temperatures and asthma due to poor air quality.

For example, the text mentions how urbanization led to tree loss, directly linking it to environmental and health degradation.

Question 20:
Analyze the given case and answer the question:

In a village, people depended on a nearby forest for firewood, fruits, and medicinal plants. Over time, excessive cutting of trees led to soil erosion, loss of wildlife, and scarcity of resources. The village council then decided to implement a tree plantation drive and strict rules against deforestation.

How did the village's dependency on the forest lead to ecological imbalance, and what steps were taken to restore it?
Answer:

The village's over-dependence on the forest caused ecological imbalance in the following ways:

  • Soil erosion: Tree roots bind soil; cutting them led to erosion, making land infertile.
  • Loss of biodiversity: Wildlife habitats were destroyed, reducing species diversity.
  • Resource scarcity: Over-exploitation caused shortages of firewood, fruits, and medicinal plants.

To restore balance, the village council took two key steps:

  • Tree plantation drive: Replanting trees helped revive the ecosystem and prevent further soil erosion.
  • Strict anti-deforestation rules: Regulations ensured sustainable use of forest resources.

This shows how community action can mitigate environmental damage.

Question 21:
Read the following case study: In a small village, people cut down trees for firewood and construction, leading to soil erosion and loss of wildlife. Based on the chapter Too Many People Too Few Trees, explain the consequences of deforestation mentioned in the case and suggest two sustainable alternatives to meet the villagers' needs.
Answer:

The case highlights the harmful effects of deforestation, such as soil erosion and loss of wildlife. When trees are cut down, the roots that hold the soil together are removed, leading to erosion. Additionally, wildlife loses its habitat, disrupting the ecosystem.

Two sustainable alternatives are:

  • Using solar energy or biogas instead of firewood to reduce dependence on trees.
  • Planting fast-growing trees for construction needs to ensure a continuous supply without harming the environment.

These measures help balance human needs with environmental conservation.

Question 22:
A city faces severe air pollution due to excessive vehicle emissions and fewer trees. Relate this scenario to the chapter Too Many People Too Few Trees and propose two solutions that individuals and the government can adopt to improve the situation.
Answer:

The scenario reflects the theme of the chapter, where overpopulation and lack of trees worsen environmental issues like air pollution. Trees act as natural air filters, and their absence exacerbates pollution from vehicles.

Solutions include:

  • Individuals can use public transport or carpooling to reduce emissions and plant trees in their neighborhoods.
  • Government can implement afforestation programs and enforce stricter emission norms for vehicles to curb pollution.

Combined efforts can restore air quality and promote a healthier environment.
