Anil Agarwal Dialogue 2022 Session : 10 The Great Extinction: The state of biodiversity

3 Mar 2022

Dhriti Banerjee Director Zoological Survey of India, Kolkata DIVERSITY = RESILIENCE • The greater the genetic diversity, species diversity, and habitat diversity in a landscape, the greater the resilience of that landscape to disturbances such as pollution, invasive species, etc. [...] – The loss of one species increases the risk of losing more species. [...] CAUSES OF MASS EXTINCTIONS Most of the extinction events are likely to have been caused by a combination of factors. [...] IIND: THE LATE DEVONIAN MASS EXTINCTION The second of the five mass extinctions. [...] THE HOLOCENE EXTINCTION • Today’s massive loss of species has been dubbed the “Holocene Extinction” (we are currently in the Holocene epoch) • Catastrophic extinctions, as was the case when an asteroid-strike wiped out the dinosaurs, actually took many thousands of years to occur.
