How do they work?Discuss the following questions in groups.1. What are some advantages of paramotors over traditional forms of water rescue? What are some disadvantages? The main advantage is the ability to spot the person who is in trouble and get there quickly. The main disadvantage is that the paramotor cannot land and pick the person up.2. As a business, how might the Para-Life rescue service make money? Is it right to charge victims for rescue? If so, how much should they be charged? What if they cannot pay?It could make money through a contract with the government. While it does not seem right to charge the victims money, in fact ambulance services, doctors, nurses, and hospitals charge victims money all the time. If people are charged money, it should be based on the time and expense required to rescue them, but that amount is hard to determine. As the victim would be billed after the rescue, if the victim cannot pay it will be just like any other bill the victim might have.3. What other interesting or new kinds of rescue are there? How do they work? One kind of rescue involves dogs that can sniff out people trapped in buildings after an earthquake. The dog just wanders over the ruined building sniffing the ground. If it smells a person, it makes a sign or begins to bark. Rescuers then know where to dig. As a person can survive for as long as three days without water, so long as the person can breathe and is not too badly injured there is still a good chance of rescue in this situation.What do you know about rip currents?Lets watch a video about rescue dogs, then talk about it.Surf the Internet for more information about Para-Life Rescue.
