A reduction in biodiversity and an increase in carbon dioxide in the atmosphere.

What does the destruction of peat bogs do?
Destruction of peat bogs and other areas of peat results in the release of carbon dioxide into the atmosphere, because the peat is removed and used in compost, the compost is decayed by microorganisms.
3 of 13
Why are trees important to preserve?
Photosynthesis locks up carbon dioxide in plants, when trees are cut down and burned or decay the carbon dioxide is released.
4 of 13
What is deforestation?
It means that many trees are cut down.
5 of 13
Why does large scale deforestation occur in tropical areas?
Because of the need for tiber and to provide land for agriculture.
6 of 13
How has deforestation increased carbon dioxide in the atmosphere?
Carbon dioxide has been released into the atmosphere due to burning of the trees or decay of the wood by microorganisms, also the rate at which carbon dioxide is removed from the atmosphere by photosynthesis is reduced.
7 of 13
How does deforestation reduce biodiversity?
There is a loss of food and habitats.
8 of 13
What purpose does deforestation serve?
Crops can be grown to produce ethanol-based biofuels and there can be increases in cattle and rice fields for food.
9 of 13
What does cattle and rice growing produce?
Methane, which has led to an increase of methane in the atmosphere.
10 of 13
What can be done to prevent the destruction of peat bogs?
Using peat-free composts.
11 of 13
Which process removes carbon dioxide from the air?
Photosynthesis.
12 of 13
Which process causes the release of carbon dioxide from peat?
Decay by microorganisms.
