Re: K-T Theories
the only problem i have with that argument, is the number of critters in the
leg. to kill off enough phytoplankton really damage the ecosystem to the
extent your idea seems to require, you'd have to destroy 1000's
of species, whereas disease at a higher trophic level does not require
so many species deaths.
i am not arguing here for the disease hypothesis, merely examining the
relative numbers involved in the food pyramid.
