Question

Quizplus · Accepted Answer

The current rate of extinction is high, and human activities (such as habitat destruction, pollution, climate change, and overexploitation) are major drivers of this crisis, threatening biodiversity at all levels. While it is true that most species on Earth have been identified, and that human responsibility for protecting endangered species is limited by factors like funding and political will, these do not fully capture why we consider current rates of extinction to be a crisis. Similarly, while plant-based medicinal compounds can contribute to plant species extinction, this is only one factor among many contributing to the broader extinction crisis. Finally, while ecological disasters like floods can certainly impact biodiversity, they are not the primary driver of the current rates of extinction.
