Sigh. This is the Nth posting that has said this, and it is utterly
and completely wrong. The point is that there is a massive difference
between organisms which are highly dependent on a restricted food and
ones that can eat most things.

When the former, whether plant, animal, fungus or other, run out of
food source, they starve and their numbers drop. The population is
thus self-limiting. That does not apply to the latter.

The only risk with such 'predators' is that they will switch to
another food, and that is PRECISELY what the scientists have been
investigating.
