Overview
One

for
each

these
8
units:
I.
THE
PHYSICAL
ENVIRONMENT
II.
THE
ORGANISM
AND

For
each

we’ll
have
explicit

upon
which
to
focus,
instead
of
digesXng
every

8. Human
ecology
of
hydrocarbons
• Each
driver’s
semester-‐long
commute
would
produce
on
average
125
kg
CO2e.
• Average
human
respiraXon
produces
about
145.6
kg
CO2e
per
year.*
• So,
each
of
our
car’s
exhaust
alone
this
semester
would
have
emiEed
almost
as
much
CO2e
as
we
each
exhale
in
an
enGre
year!
• This
exemplifies
the
disproporXonate
ecological
impact
of
each
of
our
individual
acXviXes
on
local
through
global
scales.
• Without
ecologically-‐conscien1ous
decisions
and
ac1ons,
we
collecXvely
threaten
individual
organisms,
populaXons,
species,
ecological
communiXes,
ecosystems
and
potenXally
our
enXre
planet’s
life
support
system.
(That’s
a
key
sub-‐text
for
the
next8weeks…)
