In both passages, the authors discuss the potential benefits of cloning animals, highlighting scientists' aspirations to address environmental issues and restore ecosystems. In “Lower the Greenhouse Effect: Clone Mammoths,” Samuel Viler argues that cloning mammoths could help combat climate change by restoring tundra ecosystems, which would ultimately reduce greenhouse gas emissions. He mentions how reintroducing these large herbivores might contribute to maintaining the grasses that sequester carbon dioxide.
On the other hand, in “By Phillip Jones,” the author emphasizes the emotional and ecological significance of cloning endangered species, like the passenger pigeon, to restore balance in their respective ecosystems. Jones points out that reviving such species could have positive ripple effects, potentially leading to healthier environments.
Together, these passages illustrate that scientists believe cloning could play a crucial role in ecological restoration and fighting climate change, as they aim to revive both extinct and endangered species for the benefit of our planet.
