...future metropolis was still an insignificant place. On the death in 1263 of Alexander Nevsky, who had defended Novgorod from the attacking Swedes and Teutonic Knights, the division of his lands gave the 500-sq.-mi. principality of Moscow to his youngest son Daniel. This son and his successors began buying and occasionally seizing more land, and unlike most Russian princes, they used primogeniture to preserve what they acquired. Ivan I, who became Grand Prince of Moscow in 1328, increased his territory fivefold, and the Metropolitan of the Russian Orthodox Church moved his headquarters there...
Despite assurances that the insecticide poses no threat to humans, many people object to the state's program of spraying malathion from helicopters over a 400-sq.-mi. area that includes Los Angeles and Orange counties.

Despite the objections, Governor George Deukmejian plans to continue the spraying. Pasadena is considering filing misdemeanor charges against the pilots involved in the anti-medfly mission...

Working by night, the crew plugged the hole within four hours, but an estimated 300,000 gal. of crude poured into the Pacific.

Thus was created the world's largest stretch of inhospitable land. Precipitation is so sparse over Antarctica's 14 million sq. km (5.4 million sq. mi.) that it is classified as one of the world's dryest deserts. Because most of the small amount of snow never melts and has accumulated for centuries, 98% of Antarctica is permanently covered by a sheet of ice that has an average thickness of 2,155 meters (7,090 ft.). That accounts for 90% of the world's ice and 68% of its fresh water. Although the sun shines continuously in the summer months...
...stop the bugs, the food and agriculture department has ordered a series of further aerial sprayings of Malathion over a 270-sq.-mi. area of Los Angeles and Orange counties. Beginning this week, 28 communities with a total population of 1 million will be sprayed by low-flying helicopters. If the plan , runs its course, there will be a total of eight to twelve treatments over the next five months...
