Scientists currently estimate that more than 99 percent of species that have ever lived have already gone extinct. We are part of those rare few species that get to keep holding on to life for a bit longer, but that might not be the case much longer because some scientists think we may be heading for a Sixth Extinction.

Scientific history declares five major mass extinctions in the geological time scale and with the rapid increases in extinction rates now, a Sixth Extinction seems like a not so distant future…

Tonight PNM host Kai Brito speaks with Marge Gibson, Director and founder of the Raptor Education Group about her work to combat species extinction and preserve Wisconsin’s wildlife.
