which cover about 30% of the Indian sub continent. There is an equivalent
area known as the Siberian Trapps. The Deccann trapps straddle the KT
boundary but their activity increased significantly after the impact.
Interestingly enough, at the time of the KT boundary formation, India, as a
separate continent, was almost exactly opposite the impact site in Yucatan.
(Plate tectonics). Shock waves would have spread out from the Yucatan impact
point and re-concentrated at a geologically unstable area on the other side
of the globe, causing massive volcanism.
The level of geological violence involved beggars the imagination. Imagine
hundreds of the worst volcanic eruptions we have seen over the past decades
all happening simultaneously, and you get some idea. This, in conjunction
with the effects of the Yucatan impact, turned our planet into hell
overnight.
The fact is that after the KY event and the Deccann eruption, the dinosaurs
were gone, as well as any other land animal that weighed more than a couple
of pounds. The dinosaurs were the most successful group of animals ever to
inhabit the earth, and they disappeared effectively overnight. An
equivalent extinction occurred in the oceans.
Compared to this kind of violence, our feeble attempts to modify the planet,
for good or bad are utterly insignificant. Raising the water table in one
area or stopping desertification of sub Saharan Africa are certainly worth
while endeavors, but they won't be much use inthe face of the results of a
comet impact. And if you think that comets don't hit planets, just look at
the Shoemaker-Levy impact on Jupiter.
There's nothing deliberately hostile to us in all this. But if we're in the
wrong place, planet Earth, at the wrong time ;comet impact, viral plague
outbreak, massive volcanism, global ice age, all of which have happened
before, we won't really stand much of a chance.
I'd still like a definition of "meta-species" and some information about
that event which killed off 90% of the human race, assuming that such an
event occurred.
This has got a long way from electronics, but it has been interesting. I
guess that is one reason these posts aren't particularly moderated.

The Deccann Traps are an area of volcanic flow lava, several miles thick
which cover about 30% of the Indian sub continent. There is an equivalent
