I read in
the Walnut Street Gazeout (should be Gazette) that scientists are worried
because the earth's spinning rate is slowing down. Days and nights are getting
longer. But that's not the major concern. The big problem is that the earth is
spinning like a top, and as it slows down it will start to wobble. The poles will tilt nearer the sun in their
arcs, and all the ice will melt.
The seas
will rise and become diluted with fresh water.
Lots of land will be inundated and not longer habitable for humans. Lots
of marine plant life and mammals will die out completely. In short, it will be
a disaster.
Now it
occurs to me as I lie here staring at the ceiling that is it perfectly normal
that the earth's spinning should slow down as it gradually loses the energy
that started it spinning in the first place. But, as usual, Nature has been
compensating. Gravity has been moving the high spots of the earth down to the
low spots of the earth ever since the Big Bang.
So the radius of the earth from mountain tops on one side to mountain
tops on the other side has been shrinking.
Thus, as a ballerina spins faster when she pulls her arms to her sides,
the earth has gradually tried to spin faster to make up for the slowing down
caused by waning energy. Thus the rate
of spinning has remained more or less equal in all the earth's life.
But now,
quite suddenly in cosmic terms, the earth is slowing. And I believe I know why. Let me explain. As
you know, the earth spins from east to west. As it spins, the surface of the
earth encounters resistance from the atmosphere. Once again, over the eons, this resistance
has been lessened by gravity's habit of smoothing out mountain tops and generally
sanding things down nice and smooth.
But in
recent years this resistance has increased because of windmills and yachts.
Never before
in the history of the earth have there been so many manmade things sticking up
from the surface of the earth, all of them designed deliberately to encounter
the atmosphere with force. Never before
have so many wind farms and private sailboats offered resistance to the
atmosphere. The surface of the earth is
now fatally roughened by these foreign protrusions
which, in
extracting energy from the atmospheric winds, also serve to retard the earth in
its spinning.
If we are to
save our dear earth for future generations, it is obvious that both windmills and
sailboats must be banned.
Oh yes, I
can imagine the chorus of protests from rich yachtsmen who don't give a damn
for the rest of us as long as they can pursue their sybaritic pastimes without
restriction, but we are talking survival here.
I have already contacted my senator regarding having yachting made
illegal in my state and I expect other states to follow suit once my discovery
is made general knowledge. The future of the human race depends on it.
Yours in
great apprehension etc.

'Lifer' can rest assured that I leave the Earth as I found it: I make sure to sail as many downwind legs as upwind legs.
;^)
Not a great idea to ban sailing.
