Discuss the effects of deforestation on the following.
(a) Wild animals
(b) Environment
(c) Villages (Rural areas)
(d) Cities (Urban areas)
(e) Earth
(f) The next generation
Answer
Wild animals
In forests, due to deforestation, the plants and trees are removed.
Animals are dependant on plants for their food and living
If the habitat of wild animals is destroyed, it will lead to a decrease in the number of wild animals.
And gradually, the animals will become extinct
Environment
Increase in Temperature and Global Warming
We know that Plants and trees consume carbon dioxide during photosynthesis.
If there are no trees, it will lead to more carbon dioxide in atmosphere
This Carbon Dioxide trap heat rays from sun.
This will lead to increase in temperature of earth and can cause global warming
Increase in Pollution
We know that carbon dioxide is generated by industries and vehicles.
Plants and trees consume this carbon dioxide and help in reducing pollution
If we cut trees, it will increase carbon dioxide in atmosphere
Increase In Droughts
Increase in temperature disturbs water cycle and cause droughts (less rainfall)
Roots of tree suck water from earth’s surface
This water goes to the leaves.Due to sun,this water gets evaporated and goes to clouds
This later fall down as rain
If there are less trees,less water will go up bringing less rain
Desertification
Roots of trees bind soil together
Due to less trees,there will be more soil erosion(fertile soil is eroded by wind and water).Hence fertile lands will soon turn into deserts
Villages (Rural areas)
Trees help prevent soil erosion
- Roots of trees bind the soil together.
- During heavy rains, trees protect the top soil as it provides a shelter, so that it doesn’t erode away
Without plants and trees, the top layer of the soil (which has most nutrients) will be easily removed due to various factors like wind, water etc. Since the soil loses its fertile layer, crops would not be able to grow there. So, villages won’t be able to do agriculture which will affect the living of the villagers
Cities (Urban areas)
Increase in Pollution
We know that carbon dioxide is generated by industries and vehicles.
Plants and trees consume this carbon dioxide and help in reducing pollution
If we cut trees, it will increase carbon dioxide in temperature
Deforestation will lead to global warming
This will lead to melting of glaciers
Areas near sea will sink in water
Earth
Animal and Plant Life is Affected
Natural Habitat (living area) of wild Animals and plants is disturbed.
In case of deforestation,there will be less forests,so these plants and animals will become extinct (die because of shortage of food )
So flora and Fauna is disturbed
The next generation
Many forest produce will not be available
Example Food,Wood,Many Medicines
Increase In Droughts
Increase in temperature disturbs water cycle and cause droughts (less rainfall)
Roots of tree suck water from earth’s surface
This water goes to the leaves.Due to sun,this water gets evaporated and goes to clouds
This later fall down as rain
If there are less trees,less water will go up bringing less rain
Desertification
Roots of trees bind soil together
Due to less trees,there will be more soil erosion(fertile soil is eroded by wind and water).Hence fertile lands will soon turn into deserts
Flooding of Rivers
During heavy rain,roots of trees help the soil to absorb water
However,in case of shortage of trees,soil will not be able to absorb water
This water will flow into rivers causing floods leading to loss of life and property
