Which of the following is the benefit(s) of reforestation?

i. Reduction in global warming
ii. Prevention of soil erosion and floods
iii. Decrease in biodiversity

There are several advantages of reforestation.

Global warming mitigation: Trees absorb carbon dioxide from the atmosphere which helps to mitigate the effects of global warming.

Soil erosion and flood prevention: Roots of trees penetrate deep into the topsoil and hold them tightly. This stabilises the soil, thereby reducing the risk of soil erosion. They slow the flow of water and prevent the severity of floods. The roots can absorb water, thus reducing surface runoff.

Reforestation can help in the flourishing of biodiversity in a region.
