> tourists/visitors harming the wildlife habitat (i.e. disturbing the animals, causing them stress and intimidation)
> tourists/visitors dropping litter
> tourists/visitors activities (i.e. trampling the vegetation in fields/forests, by straying off the trail)
> With regard to the see, divers and snorkellers sometimes intentionally remove pieces of coral, or even just accidentally kick or bump against it. Boaters frequently run aground or drop anchor on fragile ecosystems such as coral reefs.
