q13. READING

[1] Wolf Mountain is surrounded by beautiful forests, large fields, and high mountains. But people don't come here for the views.

[2] Here you will find Wolf Mountain Sanctuary, where Tonya Carloni cares for wolves such as the white wolf, the gray wolf, and the ambassador wolf. Although the area is big, wolves need a lot of space, and Tonya is sad that the animals must live in a closed area. She explains, however, that they would not live long in the wild.

[3] The wolves here are provided with care and food because they are, for instance, unloved pets, old movie animals, or not wanted by animal breeders. Other examples of wolves not wanted are those that are mixed with dogs or coyotesmeaning they are wolf hybrids.

[4] Wolves are also connected to fear, bad luck, and the killing of farm animals. Because of these fears, people are unhappy with Tonya's work. They have attacked her property and tried to free or kill the wolves.

[5] Tonya faces other problems too. She feeds her ten wolves red meat, chicken, and turkey. But wolves need a lot of food, and costs are $1,500 a week. Another example of a problem is that the sanctuary has very few visitors. Although artists, cinematographers from film studios, and photographers come, they do not help finance the sanctuary.

[6] As well as saving the animals, Tonya hopes to educate people: only 4% of farming livestock killed is actually due to wolvesmost are killed by coyotes, cougars, and bears.
