oliteness can also be dangerous. Typical examples are the driver who
brakes violently to allow a car to emerge from a side street at solne hazard to following traffic,
when a few seconds later the road would be clear anyway; or the man who waves a child across a
zebra crossing into the path of oncoming vehicles that may be unable to stop in time. The same
goes for encouraging old ladies to cross the road wherever and whenever they care to. It always a-
mazes me that the highways are not covered with the dead bodies of these grannies.
A veteran driver, whose mallners are faultless, told me it would help if motorists leamt to
filter correctly into traffic streams one at a time without causing the total blockages that give rise
to bad temper. Unfortunately, modern motorists can' t even learn to drive, let alone master the
subtler aspects of roadsmanship. Years ago the experts warned us that the car-owrner-ship explo-
sion would demand a lot more give-and-take from all road users. It is high time for all of us to
take this message to heart.

In the atmosphere, carbon dioxide acts rather like a one-way mirror--the glass in the roof of
a greenhouse which allows the sun's rays to enter but prevents the heat from escaping.
According to a weather expert' s prediction, the annosphere will be 3C warmer in the year
2050 than it is today, if man continues to burn fuels at the present tate. If this warming up took
place, the ice caps in the poles would begin to melt, thus raising sea level several metres and
severely flooding coastal cities. Also,
