题目材料：

Widespread climate change challenges a traditional notion that preserving specific chunks of land is an adequate way to protect endangered species. Commitment to particular places has taken conservation a long way, but it works only when the climate is relatively stable. When climate change rather than degraded habitat threatens a species` survival in a particular location, moving the species to new locales might become one way of preserving it. Some ecologists argue that such assisted migration is simply a way to mimic the natural process of dispersal: its adherents intend to transport species from places that have become uninhabitable through places that humans have made impassable. Although it has its risks, assisted migration may be a necessary step in the evolution of conservation.

The passage suggests that, in order to adapt to changing conditions, conservationists should

Areformulate their goals regarding the preservation of species
Bturn their attention to reversing climate change
Cend the practice of labeling certain species as endangered
Dreconsider the measures they use to protect endangered species
Erely on natural processes of dispersal and change
