As a result of human activities the forest cover of the earth is depleting day by day. Continuous deforestation causes negative impacts that affect the life existing on earth. These effects are global warming, greenhouse effect, loss of species, soil erosion, disruption of water cycles and many more. The forest cover on Earth plays a very significant role in controlling Climate change problems. Forests are the source of natural carbon sequesters as they help in removing excess of carbon-di-oxide from the atmosphere by maintaining the optimum level that is necessary for the survival of life on the earth. Forests play a critical role in mitigating climate change because they act as a carbon sink—soaking up carbon-di-oxide that would otherwise be free in the atmosphere and contribute to ongoing changes in climate patterns. Deforestation undermines this important carbon sink function. It is estimated that 15% of all greenhouse gas emissions are the result of deforestation.
Tropical rainforest on Earth can store more than 210 gigatons of carbon from atmosphere thus help in moderating the problem of global warming and greenhouse effect (https://www.worldwildlife.org/threats/deforestation). Thus planting more trees can effectively help in reducing the excess of CO2 from atmosphere and thus contributes in lowering global warming
