B7- Deforestation And Land Use Flashcards
What is deforestation?
Chopping down trees to clear land for various purposes
Includes activities such as agriculture, urban development, and biofuel production.
What are some common reasons for deforestation?
To clear land for farming and to grow crops for biofuels
Examples include cattle farming and rice cultivation.
What is the effect of deforestation on carbon dioxide levels?
Less carbon dioxide is taken in, leading to more CO2 in the atmosphere
This contributes to global warming and climate change.
How does deforestation lead to more carbon dioxide in the atmosphere?
Trees release CO2 when burnt and decomposing wood emits CO2
Carbon in wood contributes to atmospheric pollution once released.
Define biodiversity.
The variety of different species in an ecosystem
Greater biodiversity indicates a healthier ecosystem.
What happens to biodiversity when habitats like forests are destroyed?
Biodiversity is reduced, risking extinction of species
Forests contain numerous species; their destruction threatens many.
What are peat bogs?
Acidic and waterlogged areas where plants do not fully decay
Partly-rotted plants accumulate to form peat.
Why is peat important for carbon storage?
It stores carbon from plants instead of releasing it into the atmosphere
This prevents immediate carbon emission when plants die.
What is a consequence of draining peat bogs?
Increased contact with air leads to decomposition and CO2 release
Microorganisms respiring in peat contribute to global warming.
Fill in the blank: Deforestation leads to _______ due to habitat destruction.
less biodiversity
True or False: Peat is being used faster than it can form.
True
This unsustainable use of peat impacts carbon storage.
What happens to carbon when peat is burned?
Carbon dioxide is released into the atmosphere
This adds to global warming.
List three consequences of deforestation.
- Less carbon dioxide taken in
- More carbon dioxide in the atmosphere
- Less biodiversity
Fill in the blank: Cutting down trees reduces the amount of _______ removed from the atmosphere.
carbon dioxide
