Many ethical dilemmas faces those who seek to preserve endangered species, and especially those who wish to preserve them or reintroduce them into their natural habitats. In some cases, it is human beings who have so encroached upon these habitats that the animals being protected or reintroduced—such as elephants, wolves, and tigers—pose a potential threat to crops, livestock, and even humans themselves. In other situations, it is other species introduced into particular habitats by humans that have caused native species to become endangered. In such cases, the only means of successfully reintroducing or maintaining native species is through the complete eradication of the invading species. What are those concerned with the preservation of native species to do in such situations? Dr. Robert Wiese will address these issues and more, especially as they relate to Rachel Carson’s Silent Spring.
