The flow chart shows 'trampling', the negative effect of tourists walking in the countryside for the environment. Summarize the information by selecting and reporting the main features.

The diagram provides information about how tourists' trampling ruin the countryside environment. Overall, the trampling process has a detrimental impact on both the soil and vegetation quality. Such environmental damages are illustrated through a simple five-stage flow chart. Firstly, trampling occurs when tourists walk about the destination and flatten the grass under their shoes. These activities pose two unfavorable effects on the environment. The first one is the damage to natural plants. Those plants could become weaker as well as lose their capabilities to grow or reproduce. Therefore, the vegetation in the countryside is declining significantly. The other environmental consequence of tourists walking is the hardening of soil, which causes a noticeable reduction in the air and water quality in it. As a result, water runs off the land, and erosion rises significantly. The standard of land impacts the development of greeny. Hence, plants do not grow and reproduce, which means a reduction of vegetation. In the end, the countryside area has to suffer from not only erosion but also decreased quality of soil and vegetation.
