Part 4/10:
The extinction of apex predators like the phocine and undermined species like the passenger pigeon has had cascading effects on their respective ecosystems. For instance, within Tasmania, the removal of the thylacine has led to population booms of smaller marsupials like wallabies, resulting in diminished vegetation and a host of ecological problems. Recent research has suggested that reintroducing such species could help control overpopulation, indicating how a restoration of lost fauna might mitigate ongoing environmental issues.
