Warnings and education campaigns for sun avoidance are okay for humans, but
what about the frogs laying their eggs in high mountain ponds and streams as
they have for millennia, or the phytoplankton in the seas seeking the sun to
run their photosynthetic production, or the trees rooted in the earth and
stretching their leaves or needles skyward to the sun? They cannot avoid the
noonday sun, or slip on a shirt or hat, or use sunscreen, or be brought
indoors. They must be protected from further exposure to UV-B radiation. This
can only be accomplished through a concerted human effort to eliminate the
release of those chemicals which destroy the ozone layer.
