What is the importance of the South China tiger? The South China tiger holds a place of honor in China—as a cultural icon in art, literature, and philosophy, as a symbol of wilderness to promote a new conservation ethic amid an expanding human population, and as a source of national pride as the only uniquely Chinese tiger subspecies.
Why should we save South China tigers? By protecting an apex predator carnivore, we are protecting its prey and the entire food chain – the complete biodiversity of its ecosystem. Restoring the tiger means restoring its habitat. South Africa was chosen for its relatively cheaper land, abundant prey, conservation expertise and wildlife management skills.
Why is species extinction bad for humans? Scientists have also discovered links between the incidence of West Nile virus and hantavirus and local reductions in biodiversity. Animal extinctions may also rob humans of valuable medical advancements. Many different species have unique bodily processes that can offer insight into curing human disease.

why is bee extinction bad?
Without bees, they would set fewer seeds and would have lower reproductive success. This too would alter ecosystems. Beyond plants, many animals, such as the beautiful bee-eater birds, would lose their prey in the event of a die-off, and this would also impact natural systems and food webs.
why did dire wolves go extinct?
Most scientists agree that the dire wolf specialised in hunting large herbivores, many of which – including horses, bison and camels – became extinct or drastically declined in North America around 13,000 years ago. The disappearance of their prey almost certainly drove the dire wolf extinct.

Why are panda bears almost extinct?

Large galaxy clusters contain both dark matter and normal matter. The immense gravity of all this material warps the space around the cluster, causing the light from objects located behind the cluster to be distorted and magnified. This phenomenon is called gravitational lensing.
What was the cause of the Late Devonian extinction?
There is also evidence that extinctions may be associated with rapid global warming or cooling. Particularly in the Late Devonian, extinction events may relate to periods of abrupt cooling associated with the development of glaciers and the substantial lowering of sea level.
What is the human impact on extinction?
The authors say they found overwhelming evidence that human activities are behind nature’s decline. They ranked the major drivers of species decline as land conversion, including deforestation; overfishing; bush meat hunting and poaching; climate change; pollution; and invasive alien species.
