Answer 1

The sentence that best expresses the main idea of the article is "Some ecologists want to reintroduce endangered wildlife in North America, while others worry about the dangers," as it captures the essence of rewilding and the debates surrounding it.

Step-by-step explanation:

The main idea of the article revolves around the concept of rewilding in North America, where the objective is to restore biodiversity and ecological resilience by connecting severed habitats and by reintroducing fauna to places where they historically roamed. This approach includes large-scale efforts, as seen in projects such as the Wildlands Network, which aims to create extensive habitat networks. Moreover, the article discusses both the ecological and economic benefits of rewilding, as well as the potential risks it poses, such as the spread of diseases and increased conflict with human activities like livestock herding.

Given this context, the sentence that best expresses the main idea is: "Some ecologists want to reintroduce endangered wildlife in North America, while others worry about the dangers." This sentence encapsulates both the aim of rewilding proponents to reintroduce important ecological players and the concerns of opponents regarding potential negative impacts.
