Are humans responsible for all extinctions?

Humans are not responsible for all extinctions, as natural processes have historically led to species loss, such as climate change, volcanic eruptions, and asteroid impacts. However, human activities, including habitat destruction, pollution, overfishing, and climate change, have significantly accelerated the rate of extinction in recent times. Many current extinctions are directly linked to human actions, making us a major driver of biodiversity loss today. Overall, while not solely responsible, humans play a crucial role in the ongoing extinction crisis.
