"The Antarctic is the vast source of cold on our planet, just as the sun is the source of our heat, and it exerts tremendous control on our climate," [Jacques] Cousteau told the camera. "The cold ocean water around Antarctica flows north to mix with warmer water from the tropics, and its upwellings help to cool both the surface water and our atmosphere. Yet the fragility of this regulating system is now threatened by human activity." From "Captain Cousteau," Audubon (May 1990):17.

The region of Antarctica is an enormous foundation of icy water on planet earth, and our climate relies greatly on it. The currents that flow from Antarctica north towards the tropics, carry cold water, and when reaching their destination, blend with the warmer waters and the gushing contributes to the cooling of both our enviornment and the shallow waters. But thanks to human commotion, this vulnerable, modifiable system is now found threatened.

The twenties were the years when drinking was against the law, and the law was a bad joke because everyone knew of a local bar where liquor could be had. They were the years when organized crime ruled the cities, and the police seemed powerless to do anything against it. Classical music was forgotten while jazz spread throughout the land, and men like Bix Beiderbecke, Louis Armstrong, and Count Basie became the heroes of the young. The flapper was born in the twenties, and with her bobbed hair and short skirts, she symbolized, perhaps more than anyone or anything else, America's break with the past. From Kathleen Yancey, English 102 Supplemental Guide (1989): 25.

During the 1920´s drinking was considered ilegal, but at that time, the law was just a gag, for it was quite evident to everyone that there was a local pub, where alcahol was cosumed. These were the years in which the cities were under the domain of delinquency, and the authorities were helpless and ineffective. new genres of music such as jazz expanded all over the land, whilke classical music was slowly erased, and people such as Louis Armstrong, Count Basie and Bix Beiderbecke became the idols of our youths. A feminine movement emerged during this time, and with her mini skirt and bobbed haircut, she came to represent more than anything, maybe, America´s parting with history.

Of the more than 1000 bicycling deaths each year, three-fourths are caused by head injuries. Half of those killed are school-age children. One study concluded that wearing a bike helmet can reduce the risk of head injury by 85 percent. In an accident, a bike helmet absorbs the shock and cushions the head. From "Bike Helmets: Unused Lifesavers," Consumer Reports (May 1990): 348.

From over the 1000 lives that were caused by bycicling accidents every year, 75% were due to injuries to the head. 50% of those who have been killed, are school-aged kids. Through studies, professionals came to the conclusion that the use of a helmet, even a bike one, can decrease the threat of grave head damage by up to 85%; for in a bike misfortune, the helmet takes in the shock and protects the head by padding it.
