OBJECTIVE FORESTRY

Detailed explanation-1: -We know that trees transpire and play an important role in the water cycle as it adds moisture to the air which brings rainfall. So if the number of trees decreases the process of transpiration and water cycle will be disturbed hence the rainfall will be reduced.

Detailed explanation-2: -All that water vapor rising from the forest feeds moisture-laden clouds while also causing convection. Together, these effects accelerate the formation of rain, which falls to the soil and gets taken up all over again. This cycle of absorption, evaporation, and rain happens everywhere there are plants.

Detailed explanation-3: -The air caused by the moving of plants and trees helps in the chemical reaction with clouds that are full water loaded thereby bringing rain to the earth. Thus plants play an important role in getting more rain.
