War On Drugs: A Losing Battle?
War On Drugs: A Losing Battle? In 1968, when American soldiers came home from the Vietnam War addicted to heroin, President Richard Nixon initiated the War on Drugs. More than a decade later, President Ronald Reagan launches the South Florida Drug Task force, headed by then Vice-President George Bush, in response to the city of Miami?s demand for help. In 1981, Miami was the financial and import central for cocaine and marijuana, and the residents were fed up. Thanks to the task force, drug arre

The Beak Of The Finch
The Beak of the Finch The Bogus Logic of The Beak People who have served in the Armed Forces may be familiar with the expression, If you can't dazzle then with your brilliance, baffle them with your baloney. The Beak of the Finch uses such laughable logic, it is remarkable that anyone would believe it. The book does such a terrible job of presenting a case for evolution and history, that the only logical conclusion is that the book's true intent is to disprove it. Jonathan Weiner, The Beak of

The Wolf
The Wolf
The Wolf Destiny, perhaps from the very beginning, claimed the wolf as a symbol. Has any other animal stirred human passions the way the wolf has? Its haunting howl, its incredible stamina, its brilliant eyes, and its superiority as a predator all have been reviled as nefarious, and even demonic, traits. Ironically, these same characteristics have also been revered as belonging to a majestic, and sometimes spiritual, creature - a symbol of the magnificent, untamed wilderness. In truth, the wolf
The American Crocodile
The American Crocodile
The American Crocodile The American crocodile is a very unique animal. It is mostly found in many parts of the United States, but this species of crocodile lives in the Florida Everglades. The America crocodile's scientific name is a very complicated and confusing name. Its scientific name is Crocodylus acutus. PHYSICAL CHARACTERISTICS The American crocodile is a large reptile with a long, cigar-shaped body, short legs, and a powerful tail and deadly jaws. Its heart has four chambers, preventin

An Ecosystems Disturbance By A Pollutant
An Ecosystem's Disturbance by a Pollutant Paul Cordova L. Lehr December 11, 1995 Freedman defines a pollutant as the occurrence of toxic substances or energy in a larger quality then the ecological communities or particular species can tolerate without suffering measurable detriment (Freeman, 562). Although the effects of a pollutant on an organism vary depending on the dose and duration (how long administered). The impact can be one of sublethality to lethality, all dependent upon the factor
Integrated Pest Management
Integrated Pest Management
Integrated Pest Management Integrated pest management (IPM) is a recently developed technology for pest control that is aimed at achieving the desired control while reducing the use of pesticides. To accomplish this, various combinations of chemical, biological, and physical controls are employed. In the past, pesticides were all too often applied routinely whether needed or not. With IPM, pest populations as well as beneficial parasite and predator populations are monitored to determine whether
Purple Loosestrife
Purple Loosestrife
Purple Loosestrife The scene is breathtakingly beautiful, a thick brush of purple flowers blankets Canada's wetlands. This blanket silences the expected sounds of the wetland environment, birds chirping, ducks splashing, insects buzzing and animals thriving. This unnatural silence is disturbing, the favourite flowers that used to litter this landscape are no longer visible, the water that used to ripple continuously is perfectly still. The wetland is dead, except for this overpowering, hardy pur

Management Techniques For The Red-Cockaded Woodpecker On Federal Lands Sean Fraser NRM 304 ABSTRACT The red-cockaded woodpecker (Picoides borealis) has been listed as an endangered species since October, 1970. This species inhabits pine forests in the southeastern United States where the majority of prime timberland is privately owned. Private ownership of preferred habitat and historically destructive silvicultural practices create unique problems for federal wildlife managers. This report anal
