From the portrayal, we can conclude that the painter wants to convey such a message: a good many scenic spots are flooded with visitors, who spoil the beauty of nature by creating and leaving behind God-knows-how-much trash.

Some people, laboring under the belief that tourism serves as an engine of economic growth, seem to ignore its negative effects on the environment.

On the other hand, tourism has exerted great pressure on the environment we are living in: water is polluted, the ecological system is disturbed, and natural resources have been excessively used.
