Unit 6 Earth first SHARKS: DANGEROUS OR ENDANGERED? (P62-63) Unit 6 Understanding ideas P62-63.mp3 We see a woman swimming at night in a dark sea. Suddenly, she is pulled underwater. She surfaces, cries in fear, then disappears forever. This is the opening scene from the 1975 film Jaws, showing a shark attack. It tells the story of a great white shark that attacks and kills swimmers. Jaws was a great success, attracting huge audiences and winning many awards. It strengthened peoples long-held idea of the great white shark as a dangerous animals. People have always been scared of sharks, but Jaws made things worse. It made people frightened of sharks, especially of the great white shark. Many people who saw the film started to believe that sharks were bad animals that ate humans. Some people stopped swimming in the sea, afraid of the horrible creature from the film. Other people started fishing for sharks, killing as many as they could. At that time, nobody cared if sharks were killed, or how many were killed. People just wanted them killed. After 1975, the number of large sharks around America fell quickly, and soon fell around the world. This was not only due to fear of sharks, but also finning. Finning is a type of fishing where sharks are caught and their fins cut off. The sharks are thrown back into the sea where they die slowly and painfully. The fins are used in shark fin soup. Finning kills millions of sharks a year. Finning would have an unexpected effect upon Peter Benchley, the man who wrote the book the film Jaws was based on. In 1980, Benchley was diving when he came across an awful sight. It was an area where fishermen were finning, and the sea floor was covered with dead sharks. Benchley saw sharks being killed and this caused a deep change in him. He came to see people as a danger to sharks, rather than the other way round. From that day on, he fought to protect sharks. He admitted that his book was wrong about sharks behaviour. “Sharks dont target humans,” he said. Experts have proved that sharks do not see people as food, and they attack us by mistake. Only around six people are killed by sharks every year. Fortunately, not everyone who watched the film Jaws became afraid of sharks - some became interested in understanding them. Today, as we learn more about sharks, more people than ever want to protect them from extinction. We see a woman swimming at night in a dark sea. Suddenly, she is pulled underwater.

(P68-69) Unit 6 Developing ideas P68-69.mp3 Most of us are aware that we must take care of the environment, and the majority of us take steps to save energy and reduce waste and pollution. But recently, some “green truths” have been shown to be only half true, or even completely false. Here are some common ones. Which are really green? Paper shopping bags are better than plastic ones. Plastic bags cause litter and are a danger to wild animals, which mistake them for food. It takes hundreds of years for plastic to break down, but much less time for paper. Because of this, people think paper bags are the better environmental choice. However, making a paper bag uses four times as much energy as making a plastic bag and up to three times the amount of water. The process also produces more greenhouse gases. In fact, both kinds of bags are bad for the environment. So, take a reusable bag with you when you go shopping. When you turn off a device, it stops using power. When we turn off a device, such as television, it goes into stand-by mode. Devices in this mode still use power, and older devices in stand-by mode can use even more. This happens because electricity continues to leak from the device, even when it is turned “off”. To make sure your appliance is in fact off, remove the plug from its power supply. Eating local food is good for the environment. It seems like common sense: eating local food should be better for the environment, because it does not need to be transported long distances and kept cold during transport. Unfortunately, it is not that simple. It is the production of food, not its transport, that uses most of the energy and produces most of the greenhouse gases. In some cases, local produce might have used more energy and produced more greenhouse gases than produce grown a long way away - even taking into account its transport. Its better to take a shower than a bath. It depends on how long you spend in the shower and how large your bath is. If you spend more than eight minutes in a shower, youll use as much water as in a bath - about 50 litres of water. Therefore, the key is to keep your shower time as short as possible. Environmental awareness is now part of daily life. But its worth checking common ideas and opinions to see whats really green.
