Russian scientists work at some research stations in Antarctica. Though it's freezing cold they have to make everyday meteorological measurements. It is prohibited to kill humpback whales, they are protected by law. Marine biologists monitor the turtles on the island to find out how to protect them. When temperatures drop, birds need our help because they cannot find enough food. The sun sets in the west and that's a fact everybody knows.
