Can the presence of man cause dangerous pollution for the fauna?

It depends on how you define pollution. Certainly foreign bodies can enter the cave on the soles of shoes and in dust on clothes, but since they are mostly organic substances, they are a real feast for the fauna whose reproductive capacity was limited in the past due to the scarcity of food. Since the cave has been open to the public the number of cave dwelling animals has increased considerably.
