  Can you find out more about this?  It is very interesting also.  At
  this site do they find iridium (or other trace element anomolies?
  How did this occur?

  I would count this as a natural environmental event, but when humans
  produce it I would say it isn't.  "We" are manipulating the
  environmental system, and extinctions as a result of this are

  How true!!  Even though they are uncommon it doesn't mean that they
  are "unnatural", but "natural".  For example, when somebody
  contracts AIDS is this "unnatural" because it is uncommon?  No, it's
  juts the environment (dare I say....Mother Nature) is developing and
  expanding, and if this means than many humans, then let it be.

  All the extinctions humans have caused are not all by tools (if I
  understand exactly what you mean by tools).  Our development and
  expansion into the wildlife are killing animals, who are as a result
  trying to escape our presence and are not quick enough to adapt to
  another environmental niche.  Therefore, I beleive that it is not
  just tools but just our presence....are WE that ugly :-)

  BUT, this is "natural"...oh no I hear a revolt happening.  Perhaps
  I'm a bastard, but human activities I beleive are "unnatural" and
  until we become more intergrated with the environment then will we
  become more "natural" (not completely) in the system of the Earth.
