Your Call: Citizen Scientist: how you can become one and save threatened species

Richard Morganstein


On the September 14th edition of Your Call, Mary Ellen Hannibal discusses her new book Citizen Scientist, Searching for Heroes and Hope in an Age of Extinction.

A staggering number of fauna and flora are dying. From Alaska to Baja, virtually all of the sea starshave been wiped out. In 2015, Cassin's auklet seabirds died in record numbers. In the Sierras an unprecedented 66 million trees are dead. Currently species are going extinct all over the world, “at a rate and magnitude one thousand times faster and bigger than normal,” says Hannibal.

How are citizen scientists monitoring nature to understand and prevent species extinction? Tweet your questions and comments to @yourcallradio and join us live at 10 am with me, Rose Aguilar and you.
