Amphibians are going extinct faster than any other class of organisms in human history. Experiments suggest that some species might be able to tolerate certain pesticides in the short run. Whether that could give them enough of a cushion to adapt over the long run remains to be seen.
As conservation scientists struggle to stem the catastrophic loss of biodiversity, some synthetic biologists are working to bring extinct species back to life. Some believe it's the right thing to do to atone for driving species extinct. But many conservation biologists say it's far more important to save those still among us.
