Your comment "I love working with these huge gentle animals." Gorilla safari（觀賞野獸的旅行） Countries：Kenya，Rwanda and Uganda Departures（出發(fā)）：2—3 departures per month from Aug.jye.ai Dec. Extras：permit ￡220 If you're lucky，you'll see lions，elephants and rhinos during this safari.The highlight（最好的部分） of the trip is the opportunity to see gorillas in the mountain forests.However，you must be in good health—if a gorilla caught a cold，it would be extremely harmful to its whole family. How this vacation helps There are only about 600 gorillas left in the world as human activity has reduced the area where they can live.When you buy a permit，this will pay for the protection of the national park. Your comment "I'll surely go back as soon as I have enough money！" Polar bear watching Area & Country：Arctic，Canada Departures：sixty trips between Oct.1—Nov.19. Every October and November groups of polar bears gather in Hudson Bay.As they are normally lonely creatures，this is unusual.The bears wait for the ocean to freeze so that they can hunt for seals，so this is the perfect opportunity to see them.Extra activities include dog sledding and a night trip to see the Northern Lights. How this vacation helps If the Arctic ice cap melts due to global warming，polar bears will be in danger.We give a share of our profits（利潤） to the charity that protects polar bears. Your comment "These terrible bears get all the liquid they need from their food."
