Solution
The correct option is C Reforestation
Natural resources do not only degrade by the action of pollutants, but also by improper resource utilisation practices.
Soil is a reservoir of nutrients, it not only supplies minerals but also harbours nitrogen-fixing bacteria, holds water and acts as a matrix that stabilises the plant.
However, activities such as over-cultivation, unrestricted grazing, deforestation (clearing or thinning of forests by humans) and poor irrigation practices can remove the top fertile layers of soil and this is called soil erosion. This results in arid patches of land. When large barren patches extend and meet over time, a desert is created.
While farming, irrigation is a very important and critical step for growth of crops. Irrigation without proper drainage of water leads to waterlogging in the soil. Apart from damaging the crops, water logging also draws salt to the surface of the soil and increase in soil salinity affects crops.
Restoring a forest that existed in the past is called reforestation. It can be restored naturally in a deforested area but it takes time. However, by planting trees a deforested area can be converted into a forested area soon.
Therefore, reforestation cannot be considered as improper resource utilisation practice.
