As a business, hw might the Para-Life rescue service make mney? Is it right t charge victims fr rescue? If s, hw much shuld they be charged? What if they cannt pay?
It culd make mney thrugh a cntract with the gvernment. While it des nt seem right t charge the victims mney, in fact ambulance services, dctrs, nurses, and hspitals charge victims mney all the time. If peple are charged mney, it shuld be based n the time and expense required t rescue them, but that amunt is hard t determine. As the victim wuld be billed after the rescue, if the victim cannt pay it will be just like any ther bill the victim might have.
What ther interesting r new kinds f rescue are there? Hw d they wrk?
One kind f rescue invlves dgs that can sniff ut peple trapped in buildings after an earthquake. The dg just wanders ver the ruined building sniffing the grund. If it smells a persn, it makes a sign r begins t bark. Rescuers then knw where t dig. As a persn can survive fr as lng as three days withut water, s lng as the persn can breathe and is nt t badly injured there is still a gd chance f rescue in this situatin.
D a survey abut a new kind f rescue, and figure ut the crrect rder f the steps in the rescue service.
