after reading the novel Never cry wolf

the novel ‘never cry wolf’ I read brought me into wolf world. This is a true event.
in 1970s, government from Ottawa figured the reason why caribou’ amount declined
was on wolf’ account; therefore, people intended to hunt largely wolves so the wolf’ amount
slump sharply. At that time, the author took a very tough work to go to arctic to investigate

wolf and environment, he spent whole summer around the wolves. He watched by 15 feet
away from a wolf’ family, and he has ever exposed himself to the wolves. The wolves ignored him and he intended to attract the wolf’ notice, but the wolves still went on with politeness.
The result of study was people hunting largely made caribou reducing. A Indian hunted 200—300 caribou every year, and the Indian captured 2 caribou in a week for his 14 dogs and himself’ diet so it could be figured out how many caribous thousands of Indian killed in a year. However, as wolves, they only attack older or weak caribou and when they met herd of caribou, they watched and waited a chance, so wolves train caribou. If no wolf exists, caribou is not what caribou is now. In China of 1960s, as there were more lots of wolves in grassland, there were so much more stronger herd of horses running on the grassland. However, now almost no wolf there so no stronger horses existed. It is very sad.
