Aspirin’s origins go back at least as early as 1758. In that year, an Englishman Edward Stone noticed a distinctive bitter flavour in the bark of the willow tree. To Stone, this particular bark seemed to have much in common with “Peruvian Bark,” which has been used medicinally since the 1640s to bring down fevers and to treat malaria. Stone decided to test the effectiveness of the willow bark. He obtained some, pulverized it into tiny pieces, and conducted experiments os its properties. His test demonstrated that this pulverized willow bark was effective both in reducing high temperatures and in relieving aches and pains. In 1763, Stone presented his findings to the British Royal Society.
Several decades later, further studies on the medicinal value of the willow bark were being conducted by two Italian scientists. These chemists, Brugnatelli and Fontana, determined that the active chemicals that were responsible for the medicinal characteristics in the willow bark was the chemical saclicin, which is the active ingredient of today aspirin.
The name “aspirin” in the trade name of the drug based on the chemical salicin. Properly known as acetylsacylic acid. The trade name “aspirin” was invented for the drug in the 1890s by the Bayer Drug Company in Germany. The first bottles of aspirin actually went on sale to the public just prior to the turn of the century, in 1899.

	The rate at which the deforestation of the world is proceeding is alarming. In 1950 approximately 25 percent of the Earth’s land surface had been covered with forests, and less than twenty-five years later the amount of forest land was reduced to 20percent. This decrease from 25 percent to 20 percent from 1950 to 1973 represents an astonishing 20million square kilometre of forests. Predictions are that an additional 20 million square kilometres of forests will be lost by 2020.
	The majority of deforestation is occurring in tropical forests in developing countries, fuelled by the developing countries’ need for increased agricultural land and the desire on the part of developed countries to import wood and wood products. More than 90 percent of the plywood used in the United States, for example, is imported from developing countries with tropical rain forests. By the mid-1980s, solutions to this expanding problem were being sought, in the form of attempts to establish an international regulatory organization to oversee the use of tropical forests.
