In the Seventies
humanity suddenly
woke up to the
damage done to the
earth by the huge
explosion of new
technology in the
twentieth century.
Rowland and Molina
were among those
who helped bring
about this world-
wide ecological
awakening
#
#
The depletion of
the ozone layer
threatened to
cause an increase
in skin cancer and
cataracts, and to
affect marine life
and agricultural
crop yields.
Governments saw
the problem, but
found it hard to
establish binding
international
agreements
#
The thinning of the
ozone layer sets
alarm bells ringing
every spring in
the northern hemi-
sphere. The extent
of the problem in
the southern hemi-
sphere is even
more desperate:
between1975 and
1985 half of the
ozone over the
vast landmass
of Antarctica
disappeared
#
The implications
of both global
warming and the
ozone depletion in
the atmosphere
were so serious
that politicians -
mindful of the
burgeoning green
movement - even
promised to beat
the deadlines
which they had
set themselves
#
In both planetary
hemispheres, the
possible dangers
from the loss of
atmospheric ozone
are still being
investigated. The
consequences of
ozone depletion are
now known to be
more far-reaching
than anyone had
suspected when
the holes were
first detected
