The flow chart illustrates the environmental consequences of trampling, a process caused by tourists walking in the countryside.
Overall, it demonstrates a progressive deterioration of the soil and vegetation as a result of repeated human activity.
Initially, tourists walking over grassy areas cause soil compaction, which reduces water infiltration. Consequently, the soil becomes harder and more susceptible to erosion, impairing its ability to support plant life. As a result, vegetation gradually dies off, leaving patches of bare ground. This exposed soil is then further eroded by water and wind, which exacerbates the degradation of the local ecosystem. Ultimately, trampling initiates a self-reinforcing cycle in which both soil structure and plant cover are severely damaged.
In summary, the diagram highlights how a seemingly minor human activity can trigger a chain of environmental impacts, culminating in significant soil and vegetation loss.
