The food chain affects us all; only a few will be eaten by cannibals.
In caves, the basis of the food chain is organic matter from the surface.
These measures include the compulsory slaughter of cattle suspected of having BSE and the removal from the food chain of their milk and carcasses.
As the animals move inland to search for other food sources, a significant disruption of the ecosystem and food chain occurs.
Risks include zoonoses, changes in air quality from the burning of carcasses, and contamination of water supplies and the food chain.
