Explain how promoting 'afforestation' and checking 'deforestation' reduces the release of green house gases.

Promoting afforestation means to induce more growth of plantation and forests. This helps to absorb green house gas - carbon dioxide during photosynthesis.

$6\text{CO}$2 + 12\text{H}2\text{O} \xrightarrow[\text{Chlorophyll}]{\text{Sunlight}} \text{C}6\text{H}{12}\text{O}6 + \text{6H}\text{2}\text{O} + 6\text{O}_2

Checking deforestation means to reduce burning of forests and biomass. This helps to control the emission of green house gases.
