GCSE Biology - Land Use - Deforestation & Peat Bogs #92

The video explores the environmental impacts of human land use, focusing on deforestation and peat bog destruction. Deforestation, often for agriculture and logging, increases atmospheric carbon dioxide and reduces biodiversity. Peat bogs, crucial for carbon storage, are being drained for agriculture, releasing stored carbon and harming biodiversity. Both practices contribute to global warming and species extinction.

What is one of the main environmental consequences of converting land for human use?

• Reduced land for other organisms

• Enhanced soil fertility

• Increased biodiversity

• Improved air quality

Which of the following is a primary reason for deforestation?

• To enhance soil quality

• To promote wildlife conservation

• To clear land for farming

• To increase urban green spaces

How does deforestation contribute to global warming?

• By reducing carbon dioxide levels

• By enhancing photosynthesis

• By increasing oxygen levels

• By releasing stored carbon dioxide

What is a significant environmental benefit of peat bogs?

• They enhance water drainage

• They promote rapid plant decay

• They store carbon and reduce global warming

• They increase soil acidity

What happens when peat bogs are drained for agriculture?

• Biodiversity increases

• Soil becomes less fertile

• Carbon dioxide is stored

• Stored carbon is released as carbon dioxide
