15. Sumatran Tiger
The Sumatran tiger, the smallest surviving tiger subspecies, is critically endangered due to poaching and deforestation. These threats decimate their habitats and reduce prey availability, pushing them closer to extinction. As apex predators, Sumatran tigers play an essential role in regulating prey populations, ensuring ecological balance. Protecting these tigers is crucial for maintaining the health of their forest ecosystems and preserving the biodiversity that thrives under their influence. Addressing these threats is vital for their continued survival.
