Q: What is our role and responsibility to protect the environment? A: We play an important role in protecting the environment. Without protection for places such as the Great Barrier Reef, the habitat would soon destruct due to hunters and illegal coral smugglers. There could also be a new type of animal accidentally introduced into a habitat that would not be compatible and wreck the ecosystem. If we didn’t try to protect world heritage sites our most valued natural places would soon be left as a horrible and dog-eat-dog ecosystem. Animals previously lived quite happily without any human interference. With the age of ‘Peace and Harmony’ over people are thinking more about themselves and forgetting about the environment which could destroy the world’s natural habitat eventually. Q: What are the purposes of world and national heritage listings? A: The purpose of world and national heritage sites is to acknowledge their great nature and keep them preserved for future generations to proper and enjoy. They are also made to protect the site so hunters, animals that are non-compatible to the environment, and illegal smugglers are kept away from the unique nature. To make sure of that, there are usually park rangers who enforce the law. Take the Yellowstone Park in the United States, it is protected by about 59 ranger sites, which could be a mini police force. Although most rangers cannot arrest people, they can still give them a hefty fine. The Great Barrier Reef The Great Barrier Reef extends 2000km off the east coast of Australia. The Great Barrier Reef was made a World Heritage Site because · It has 1,500 species of fish. · It holds 4000 different types of molluscs. · It has 400 remarkable types of weird coral. · It has a good example of the earth’s evolution. · It has an example of a supernatural phenomenon. · It has an outstanding example of the ongoing biological and environmental processes in the natural world. There are not big threats to the site besides the animal smugglers. Animal smugglers are very popular in the Great Barrier Reef, as it does not have a park ranger. This then makes it vulnerable. There is also a big threat that non-adaptable animals would accidentally be released into the environment. This would mess the whole circle of life and the food chain would be left in pieces. The ocean would turn into a dog-eat-dog world. There are quite a few types of protection needed for the Great Barrier Reef. Firstly, it needs a park ranger. As it is in the water, this would be quite difficult to manage, as there is a whole 2000km to watch. A better system of doing this with modern technology would be using a satellite to check if there were any unidentified ships going into its general area. The Statue of Liberty The Statue of Liberty was made in Paris by the French sculptor Bartholdi. It was a gift from France on the anniversary of the American independence in 1886. Standing at the entrance to New York Harbour, it has welcomed millions of immigrants to the United States of America since it was opened in 1886. It is a World Heritage site as it symbolises the American independence. It was also the latest modern sculpture in the era of the 1880s. There are quite a few threats to this site. Firstly, the terrorism threat is very big and real. Someone could plant a bomb at the top of the statue and blow it to pieces. Secondly, the graffiti threat would also be big. Street thugs and gangs would go around the bottom of the statue and write nasty things on the walls. They might also write things on the stairway on the way up to the top of the statue. Some types of protection needed to guard the site would be police and security officers. The police would have to be stationed around the site at all times to make sure there would be no terrorism threats. They would also have to do a brief screening to everyone who wants to climb the statue to minimise threats. The security guards would be needed on the stairways and on the top of the statue to make sure no vandalising would occur. Security cameras would make this job a lot easier. Security has been strengthened around the statue after September 11. After the Twin Towers were hit 3 fighter jets immediately flew to protect the Statue of Liberty. Every one was also evacuated from the statue. The American public would be very worried if an important landmark such as the Statue of Liberty would be blown up. To minimise panic the statue was immediately protected as a safety precaution. Abacus - c. 3000 B.C. Transistors - 1947 Doug Engelbart - 1968 Apple II - 1977 IBM PC - 1981 World Wide Web - 1991 A HISTORY OF THE COMPUTER: PREHISTORY The abacus, a simple counting aid, may have been invented in Babylonia (now Iraq) in the fourth century B.C. The Antikythera mechanism, used for registering and predicting the motion of the stars and planets, is dated to the first century B.C. It was discovered off the coast of Greece in 1901. Arabic numerals are introduced to Europe in the eighth and ninth centuries A.D. Roman numerals remain in use in some parts of Europe until the seventeenth century. The Arabic system introduced the concepts of the zero and fixed places for tens, hundreds, thousand, etc., and greatly simplified mathematical calculations. John Napier, Baron of Merchiston, Scotland, invents logs in 1614. Logs allow multiplication and division to be reduced to addition and subtraction. Wilhelm Schickard builds the first mechanical calculator in 1623. It can work with six digits, and carries digits across columns. It works, but never makes it beyond the prototype stage. Schickard is a professor at the University of Tubingen, Germany. Blaise Pascal builds a mechanical calculator in 1642. It has the capacity for eight digits, but has trouble carrying and its gears tend to jam. Joseph-Marie Jacquard invents an automatic loom controlled by punch cards. Charles Babbage conceives of a "Difference Engine" in 1820 or 1821.
