In both passages, the authors highlight the potential benefits of cloning animals, particularly in addressing environmental issues. In Passage 1, the emphasis is on the desire to resurrect extinct species, like the woolly mammoth, to help restore ecosystems that have been disrupted by human activity. The author points out that reintroducing such species could help maintain biodiversity and stabilize environments that are currently imbalanced.
Similarly, Passage 2 discusses the cloning of mammoths specifically as a means to combat climate change. The author argues that mammoths could help lower the greenhouse effect by grazing on tundra, which would encourage the growth of grass and potentially reduce carbon dioxide levels in the atmosphere.
Together, these texts illustrate that scientists' hopes for cloning extend beyond mere curiosity; they aim to use these species to mitigate environmental problems and restore ecological harmony.
