The activities that follow ask students
to reflect on the basic
human behavior of applying categories
to the people and
things we meet and
to think about the circumstances in which «single stories» about others can
be harmful or even dangerous.
Other changes
to other parts of the system may also
be equally important
to human welfare, and additional amounts of CO2 added may
be beneficial (
to a point) or
harmful (in excess), i.e.
humans have done pretty well with CO2 in the 280 ppm range, but 180 ppm seems
to have
things a bit cold, and 400 ppm and over takes the planet into a range not seen since their Australopithecus ancestors
were roaming the planet.
