The rate of extinction is faster.
they are much lower
Mainly habitat loss and over hunting, poaching.
The sixth mass extinction differs from the past five primarily because it is driven by human activities, such as habitat destruction, climate change, pollution, and overexploitation of species. Unlike previous extinctions that were caused by natural events like volcanic eruptions or asteroid impacts, the current crisis is a result of anthropogenic influences that accelerate species loss at an unprecedented rate. Additionally, the current extinction event is occurring within a much shorter time frame, with species disappearing faster than ever recorded in the fossil record. This human-induced crisis poses significant challenges for biodiversity and ecosystem stability.
Individual organisms differ, but some of this variation is heritable. Species alive today are descended with modifications from ancestral species that lived in the distant past.

Threatend Species
Yes, Charles Darwin accepted the concept of extinction. He recognized that species could become extinct due to various factors, including environmental changes and competition for resources. In his work, particularly in "On the Origin of Species," he discussed how natural selection could lead to the decline and eventual disappearance of species that could not adapt to changing conditions. Darwin's observations of the fossil record also supported the idea that many species had existed in the past but no longer existed today.
