The
scenario
had
been
predicted
and
the
storm's
path
and
intensity
accurately
forecast.
Even
so,
when
Hurricane
Katrina
struck,
government
agencies
and
residents
alike
seemed
to

guard.

video,
a
news
correspondent
returns
to
New
Orleans

year
after
he
spoke
with
experts
about
the

an
outsider's
perspective,
storm
chasing
might
appear
to
involve
hours
and
hours
of
boredom,
accentuated
by
a
few
moments
of
unimaginable
excitement.
But
to
tornado
researchers,
the
effort
and
expense
they
expend
in
search
of
a
single
tornado-producing
storm
reflect
the
importance
of
these
events
in
terms
of
their
impact
on
lives
and
property.
This
video
segment
follows

Humans
have
had
a
greater
impact
on
forests
than
on
other
land
ecosystems.
This
interactive
feature
uses
NASA
satellite
images
taken
between
1984
and
2000
to
demonstrate
just
how
much
of
a
once
densely
forested
region
in
Bolivia
has
been
cleared
for
commercial
purposes.
Users
can
view
the
images
as
an

taken
every
two
years
to

In
addition
they
will
compare
the

of
a
variety
of
fabrics.
Throughout
this
six-day
unit,
they
collect
their
