Environmental Impact of Land Use

Why is land considered a crucial limited resource for humans?

• It is only used for waste disposal.

• It is abundant and easily accessible.

• It is used for various purposes like building and farming.

• It is not affected by human activities.

What is the primary reason for deforestation?

• To increase biodiversity.

• To reduce global warming.

• To create more urban areas.

• To clear land for farming and raising cattle.

How does deforestation contribute to global warming?

• By releasing stored carbon dioxide when trees are cut or burned.

• By creating more habitats for animals.

• By reducing carbon dioxide in the atmosphere.

• By increasing oxygen levels.

What happens to biodiversity when forests are destroyed?

• It only affects plant species.

• It decreases, leading to possible extinction of species.

• It remains unchanged.

• It increases significantly.

What are peat bogs, and why are they important?

• They are dry areas used for farming.

• They are waterlogged, acidic areas that store carbon.

• They are urban areas with high biodiversity.

• They are regions with no ecological significance.

How does draining peat bogs affect the environment?

• It creates new habitats for diverse species.

• It increases oxygen levels, aiding plant growth.

• It releases stored carbon dioxide, contributing to global warming.

• It has no impact on the environment.

What is the consequence of using peat as fuel or compost?

• It helps in reducing carbon emissions.

• It releases stored carbon dioxide into the atmosphere.

• It increases the formation of new peat bogs.

• It has no effect on carbon levels.

What is a common result of both deforestation and peat bog destruction?

• Improved air quality.

• Habitat destruction and reduced biodiversity.

• Decreased carbon dioxide levels.

• Increased biodiversity.
