John R. Love has written: 'Pollution threat'
The level of water pollution varies from water body to water body. Water pollution is a serious health threat for both animals and humans, potentially leading to sickness or even death.
Pollution describes a major threat to natural resource ecosystems, affecting air and water quality, as well as wildlife habitats. Soil can also be threatened by erosion, degradation, and contamination, impacting the health of ecosystems and their ability to support plant and animal life.
I think you ment threat to the Sphinx. Well in my opinion it would be pollution, and time.
in away there is no one common threat. most species are restricted to 2 or 3 locations. if they are disturbed by storms, overfishing, pollution, etc. then they are gone.
