The history of life on Earth is punctuated by at least five massive extinction events, some resulting in an estimated loss of 96% of species. What causes these biological catastrophes? How do we learn about them? Why do scientists think current extinctions might be comparable to these ancient events?

We'll discuss the past and explore the potential consequences of current biodiversity losses, and what we can do to mitigate or avert future losses. Speakers will include Matt Friedman of the U-M Museum of Paleontology and Department of Earth and Evironmental Sciences and Johannes Foufopoulos of the School for Environment and Sustainability.

Science Cafés provide an opportunity for audiences to discuss current research topics with experts in an informal setting. Hors d’oeuvres at 5:30 p.m.; program 6:00-7:30 p.m. Seating is limited – come early.
