Download Powerpoint of consequences of forest fires

Extinction of Species
 Deforestation, of course, causes trees to be cut or
burned down. Many animals will lose their homes and
migrate to other unsuitable environment. Some
animals are unable to adapt, and they might die easily.
Predators will of course, be introduced and the
population will be unbalanced. Thus, some animals
might die of quickly.
Greenhouse effects
 Enormous quantities of carbon dioxide are let during
forest fires. Thus while the input of carbon dioxide to
the atmosphere is increased its output decreases.
Many scientists believe that deforestation has been
contributing significant amounts of carbon dioxide to
the global atmosphere and thereby to the greenhouse
effect or global warming.
Natural Disasters
 In forest fires, global warming is caused (refer to Point
2). Of course, global warming leads to dire
consequences. Floods, droughts, earthquakes. They
can take many people’s lives, and the world is doomed.
Soil Erosion
 Trees with the help of deep root systems are able to
draw water from sub-surface water table. Humidity
prevents excessive water loss and rapid desiccation.
Plants contribute organic matter which upon
decomposition adds humus to the soil.
 Deforestation leaves the ground surface bare. Further
loss of nutrients might occur. Where remaining
vegetation is burned to clear the land and agriculture
attempted loss of nutrients is even more rapid. Already
poor tropical soil is made poorer.
Soil Erosion
 The top soil which is thus lost is irreplaceable. Nature
takes about 1000 years to produce 2.5 cms of top soil.
 Massive soil erosion aggravates flood situation in two
ways. Firstly, the deposition of silt and sediments in
river beds makes them shallow. Secondly, land devoid
of forest cover loses its water holding capacity. About
10 million hectares of forested land can hold enough
water to fill completely a reservoir as large as that of
Bhakhra-Nangal dam. In absence of plant cover this
water flows down in rapid torrents.
Haze
 Forest fires give off haze. In Indonesia, many forest
fires take place to clear land. Other nearby countries,
like Singapore and Malaysia, are also affected. Many
people can end up sick, and adults might not be able to
turn up for work. No work- disastrous economy? Like I
said earlier on, the world would be doomed.
Orangutans
 About 1000 orangutans have died during the dry
season earlier. Forest fires have produced thick smoke
across Borneo. They have suffered from dehydration,
respiratory problems, lack of food and even sustained
injuries due to the forest fires. The fires have destroyed
their habitats. Orangutans flee the burning forest in
search of food and safety, often to nearby palm oil
plantations, where they are abused. Shouldn’t
orangutans be saved? Why are they being abused? In
my opinion, the world should do something to save
these orangutans.
Thank You! If you play a part in
helping the Orangutans, we take
our hats off to you :D
