(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
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
