C Greenhouse effect is a natural phenomenon

Reforestation refers to the replanting of trees on land that has previously had trees, but where these were cut down later. Reforestation is one of the remedies to combat deforestation. Because of the increasing loss of forests, many animals and plants are losing their habitat leading to a loss in biodiversity of species. Carbon dioxide levels in the atmosphere are on an ever increasing trend because of very less plant cover left to utilise the carbon dioxide. So, reforestation is the ultimate remedy for many environmental issues.
