Smog
Smog - airborne smoke particles combined with solid and liquid fog -
could be lethal. Among numerous other substances, smog also contains
cyanide and sulfuric acid. During the autumn of 1909, there were more
than 1,000 "smoke-fog" deaths in Glasgow and Edinburgh. In 1952 smog
killed more than 4000 people in Greater London within the three weeks.
Los Angeles and Tokyo also suffer from smog pollution.
Photochemical smog has nothing to do with either smoke or fog. It
originates from nitrogen oxides and hydrocarbon emissions mainly from
cars. These then undergo photochemical reactions in the lower
atmosphere and yield the highly toxic gas ozone in the presence of
sunlight.
Smog was so severe in London well into the end of the 1970s
that winter sunshine hours were reduced by one third.

Soccer War
Wars were fought for strange reasons - but none as bizarre as the one
that led to the 4 days long skirmish between El Salvador and Honduras
in July 14, 1969.
