存在的问题●生活在澳大利亚的考拉时常面临着森林大火的威胁。它们行动缓慢,一旦遭遇森林火灾,很难及时地逃离火场。●考拉还面临病毒的威胁,一旦感染就可能导致癌症。动物园的行动●一些动物园在努力保护考拉。美国的圣地亚哥动物园在考拉保护项目中处于领先地位。他们为每一只在动物园出生的考拉都作了详细的记录。●动物园还开展了考拉病因的研究项目。
Problems ● Koalas living in Australia often face the threat of a forest fire. They are slow to act and, in the face of forest fires, find it difficult to escape from the scene in time. Koala also faces the threat of a virus that can cause cancer once it is infected. Zoo Action ● Some zoos are trying to protect koalas. The San Diego Zoo in the United States leads the koala conservation program. They made a detailed account of every Koala born in the zoo. ● Zoo also carried out the koala etiology research project.
