It is said, ‘CO2 contributes to global warming.’ Explain.


Plants utilise C02 from the atmosphere for photosynthesis, thereby decreasing the amount of CO2 in the air. Deforestation leads to an increase in

the amount of CO2 in the air because the number of trees which consume CO2, is reduced.

Human activities, thus contribute to the accumulation of CO2 in the atmosphere. CO2 traps heat and does not allow it to escape jnto space.

As a result, the average temperature of the earth’s atmosphere is gradually increasing. This is called global warming. Thus, increased

CO2 contributes to global warming.
