The leaves of a tree are always giving off moisture and this constant evaporation cools the surrounding atmosphere. In consequence when moisture-laden winds blow over a forest the moisture they carry is condensed and forms clouds and these dissolve in rain. This is not mere theory. It has been proved that the destruction of forests of any extent quickly changes the climate of the whole district. Whereas before it had an abundant rainfall after disafforestation the rainfall became scanty the land went out of cultivation and became an arid desert. On the other hand afforestation or the planting of forests will turn a desert into a well-watered and fertile district. Further forests on hill sides do much to prevent destructive floods. When heavy rain falls on bare hills it rushes down at once to the plains I roaring torrents carrying parts of the hill with it and flooding the country below.
