Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How does deforestation affect climate change
A
Trees which have been cut down can no longer remove CO2 from the atmosphere
B
Trees which have been cut down can no longer make O2
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The reason that logging is so bad for the climate is that when trees are felled they release the carbon they are storing into the atmosphere, where it mingles with greenhouse gases from other sources and contributes to global warming accordingly.

Detailed explanation-2: -When deforestation occurs, much of the carbon stored by trees is released back into the atmosphere as carbon dioxide, which contributes to climate change. In the last decade, the largest amounts of deforestation occurred across the humid tropics, mostly in Africa, followed by South America.

Detailed explanation-3: -When forests are cleared or burnt, stored carbon is released into the atmosphere, mainly as carbon dioxide. Averaged over 2015-2017, global loss of tropical forests contributed about 4. 8 billion tonnes of carbon dioxide per year (or about 8-10% of annual human emissions of carbon dioxide).

Detailed explanation-4: -Increased Carbon Dioxide Levels in the Atmosphere Forests serve as a carbon sink by absorbing atmospheric carbon dioxide during photosynthesis. Since carbon dioxide is a greenhouse gas, deforestation is a direct contributor to the greenhouse effect and (consequently) global warming.

Detailed explanation-5: -Ans. Deforestation has massively impacted the climate and atmosphere. It has also led to desertification and soil erosion, resulted in the increase of greenhouse gases and has become a threat to wildlife and animal habitats.
