NCERT VIII - Sciences

Discuss the effects of deforestation on the following.

(b) Environment:

Answer 1

deforestation will lead to global warming because,the CO2 is not absorbed by plants as a result of their exhaustion.Thus,carbondioxide gets accumulated in our atmosphere.it has an adverse effect on our environment and increase heat by trapping more amount of sun light

Answer 2

 Green plants prepare their own food. All other organisms depend for their food on green plants.Deforestation disturbs the food chain. Plants help in precipitationa and  deforestation reduces the amount of precipitation. Plants take in carbondioxide from the surrounding and release oxygen during photosynthesis and thus maintain the balance of carbon dioxide and oxygen in the environment. Deforestation disturbs this balance.
