The poisoning of the world's land, air, and water is the fastest-spreading disease of civilisation. it probably produces fewer headlines than wars, earthquakes and floods, but it is potentially one of history's greatest dangers to human life on earth. if present trends continue for the next several decades, our planet will become uninhabitable.overpopulation, pollution and energy consumption have created such planet-wide problems as massive deforestation, ozone depletion, acid rains and the global warming that is believed to be coused by the greenhouse effect.the seas are in danger. they are filled with poison: industrial and nuclear waste, chemical fertilisers and pesticides. the mediterranean is already nearly dead; the north sea is following. the aral sea is on the brink of extinction. if nothing is done about it, one day nothing will be able to live in the seas.

The White House is the official residence and principal workplace of the President of the United States, located at 1600 Pennsylvania AvenueNW in Washington, D.C. It has been the residence of every U.S. president sinceJohn Adams in 1800.

The house was designed by Irish-bornJames Hoban[2] and built between 1792 and 1800 of white-painted Aquia Creek sandstone in the Neoclassical style. When Thomas Jefferson moved into the house in 1801, he (with architectBenjamin Henry Latrobe) added lowcolonnades on each wing that concealed stables and storage.[3] In 1814, during the War of 1812, the mansion was set ablaze by the British Army in the Burning of Washington, destroying the interior and charring much of the exterior. Reconstruction began almost immediately, and President James Monroe moved into the partially reconstructed Executive Residence in October 1817. Construction continued with the addition of the semi-circular South portico in 1824 and the North portico in 1829.
