1. The notion
is that
people have failed to detect the massive changes
which have happened in the ocean
because
they have been looking back only a relatively short time into the past.
2. Those
who oppose the building of flats
base their case primarily on the assumption
that
everyone prefers an individual home and garden
and on the high cost
per unit of accommodation.
3. For example,
one graphic illustration
to which
children might readily relate
is the estimate
that
rainforests are being destroyed
at a rate
equivalent to
one thousand football fields every forty minutes
– about the duration of a normal classroom period.
4. The American economic system
is, organized around
a basically private-enterprise, market- oriented economy
in which
consumers largely determine
what shall be produced
by spending their money
in the marketplace
for those goods and services
that
they want most.
5. What should doctors say,
for example,
to a 46-year-old man
coming in for a routine physical check up
just before going on vacation
with his family
who,
though he feels in perfect health,
is found to have a form of cancer
that will cause him
to die
within six months?
