(What happens due to deforestation)



Increase in Temperature and Global Warming

We know that Plants and trees consume carbon dioxide and give out oxygen during photosynthesis.

If there are no trees, it will lead to more carbon dioxide in the 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 the atmosphere

 

Increase in Droughts

Removal of trees also 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

 

Animal and Plant Life is Affected

Animals and Birds are dependent on plants and trees for their food.

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 )

 

Shortage of Food and Forest Produce

Trees and plants in forest provide us variety of food to eat. Example- Fruits,honey etc

Also, woods obtained from trees is used to make furniture and paper etc

Many medicines are also prepared from plants and trees

So cutting of trees will lead to shortage of forest products

 

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
