A team of scientists is trying to jumpstart a global conservation movement, on par with efforts to save the rainforests or protect the oceans. But it might be even more ambitious because the target of their quest is invisible, everywhere, and mostly something we try to hand-sanitize away: microbes.So how do you conserve something that is everywhere and in everything? And why do microbes need protecting to begin with? Host Flora Lichtman digs into it with microbial ecologist Jack Gilbert, who is leading this charge. They chat about the thinking behind microbe conservation plans, and why some scientists are hesitant to jump onboard.Guest: Dr. Jack Gilbert is a microbial ecologist at the Scripps Institution of Oceanography and co-chair of the International Union for Conservation of Nature’s Species Survival Commission’s Microbial Conservation Specialist Group.
