Which of the following is NOT a direct impact of deforestation on human health?

  1. Increased risk of respiratory diseases

  2. Reduced access to clean water

  3. Increased risk of malnutrition

  4. Improved mental health


Correct Option: D
Explanation:

Deforestation can lead to increased air pollution, which can cause respiratory problems. It can also reduce access to clean water, leading to waterborne diseases. Additionally, deforestation can disrupt ecosystems, making it more difficult for people to obtain food and other resources, leading to malnutrition.

How does deforestation contribute to climate change?

  1. It releases carbon dioxide into the atmosphere.

  2. It reduces the amount of oxygen in the atmosphere.

  3. It increases the amount of water vapor in the atmosphere.

  4. It decreases the amount of sunlight reaching the Earth's surface.


Correct Option: A
Explanation:

When forests are cleared, the trees that once absorbed carbon dioxide are no longer present. This results in an increase in the amount of carbon dioxide in the atmosphere, which contributes to climate change.

Which of the following is NOT a consequence of land use changes?

  1. Habitat loss for wildlife

  2. Increased soil erosion

  3. Improved air quality

  4. Reduced water pollution


Correct Option: C
Explanation:

Land use changes, such as deforestation, can lead to habitat loss for wildlife, increased soil erosion, and reduced water quality. However, they do not typically lead to improved air quality.

How does deforestation affect the availability of clean water?

  1. It reduces the amount of water available for drinking and irrigation.

  2. It increases the amount of water available for drinking and irrigation.

  3. It has no impact on the availability of clean water.

  4. It improves the quality of water available for drinking and irrigation.


Correct Option: A
Explanation:

Forests play a crucial role in the water cycle. They help to regulate the flow of water, prevent soil erosion, and filter pollutants. When forests are cleared, the amount of water available for drinking and irrigation is reduced.

Which of the following is NOT a potential health impact of air pollution caused by deforestation?

  1. Increased risk of respiratory diseases

  2. Increased risk of cardiovascular diseases

  3. Improved mental health

  4. Increased risk of cancer


Correct Option: C
Explanation:

Air pollution caused by deforestation can lead to increased risk of respiratory diseases, cardiovascular diseases, and cancer. However, it does not typically lead to improved mental health.

How does deforestation affect biodiversity?

  1. It reduces biodiversity.

  2. It increases biodiversity.

  3. It has no impact on biodiversity.

  4. It improves biodiversity.


Correct Option: A
Explanation:

Forests are home to a wide variety of plant and animal species. When forests are cleared, these species lose their habitat and are at risk of extinction. This leads to a reduction in biodiversity.

Which of the following is NOT a potential consequence of land use changes on human health?

  1. Increased risk of infectious diseases

  2. Increased risk of non-communicable diseases

  3. Improved mental health

  4. Increased risk of malnutrition


Correct Option: C
Explanation:

Land use changes can lead to increased risk of infectious diseases, non-communicable diseases, and malnutrition. However, they do not typically lead to improved mental health.

How does deforestation affect the soil?

  1. It increases soil erosion.

  2. It reduces soil erosion.

  3. It has no impact on soil erosion.

  4. It improves soil fertility.


Correct Option: A
Explanation:

Forests help to hold soil in place and prevent erosion. When forests are cleared, the soil is exposed to wind and rain, which can cause erosion. This can lead to a loss of soil fertility and a decrease in crop yields.

Which of the following is NOT a potential impact of climate change on human health?

  1. Increased risk of heat-related illnesses

  2. Increased risk of vector-borne diseases

  3. Improved mental health

  4. Increased risk of respiratory diseases


Correct Option: C
Explanation:

Climate change can lead to increased risk of heat-related illnesses, vector-borne diseases, and respiratory diseases. However, it does not typically lead to improved mental health.

How does deforestation affect the livelihoods of people who depend on forests?

  1. It reduces their access to food, water, and other resources.

  2. It increases their access to food, water, and other resources.

  3. It has no impact on their livelihoods.

  4. It improves their livelihoods.


Correct Option: A
Explanation:

Forests provide a wide range of resources that people depend on for their livelihoods, such as food, water, timber, and fuel. When forests are cleared, people lose access to these resources, which can have a devastating impact on their livelihoods.

Which of the following is NOT a potential consequence of land use changes on ecosystems?

  1. Habitat loss for wildlife

  2. Increased biodiversity

  3. Disruption of ecosystem services

  4. Reduced water pollution


Correct Option: B
Explanation:

Land use changes can lead to habitat loss for wildlife, disruption of ecosystem services, and reduced water pollution. However, they do not typically lead to increased biodiversity.

How does deforestation affect the global carbon cycle?

  1. It releases carbon dioxide into the atmosphere.

  2. It absorbs carbon dioxide from the atmosphere.

  3. It has no impact on the global carbon cycle.

  4. It reduces the amount of oxygen in the atmosphere.


Correct Option: A
Explanation:

When forests are cleared, the trees that once absorbed carbon dioxide are no longer present. This results in an increase in the amount of carbon dioxide in the atmosphere, which contributes to climate change.

Which of the following is NOT a potential impact of climate change on ecosystems?

  1. Habitat loss for wildlife

  2. Increased biodiversity

  3. Disruption of ecosystem services

  4. Reduced water pollution


Correct Option: B
Explanation:

Climate change can lead to habitat loss for wildlife, disruption of ecosystem services, and reduced water pollution. However, it does not typically lead to increased biodiversity.

How does deforestation affect the local climate?

  1. It increases the temperature.

  2. It decreases the temperature.

  3. It has no impact on the local climate.

  4. It improves the air quality.


Correct Option: A
Explanation:

Forests help to regulate the local climate by providing shade and releasing water vapor into the atmosphere. When forests are cleared, the temperature increases due to the loss of shade and the release of heat from the sun.

Which of the following is NOT a potential consequence of land use changes on human well-being?

  1. Increased risk of food insecurity

  2. Increased risk of water scarcity

  3. Improved mental health

  4. Increased risk of poverty


Correct Option: C
Explanation:

Land use changes can lead to increased risk of food insecurity, water scarcity, and poverty. However, they do not typically lead to improved mental health.
