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 temperature

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
