Uncertainty of outcomes is a feature of conservation. That's perhaps why the "precautionary principle" is held so sacred in this field. But, considering the potential cost of inaction in a rapidly-changing world, are we being a bit too cautious? Michelle Marvier and Peter Kereiva recently tackled this topic, and Michelle discussed it with me on the podcast.Michelle Marvier is a professor in the Department of Environmental Studies & Sciences at Santa Clara University. She has authored and co-authored a textbook in Conservation Science and more than 60 peer-reviewed articles and book chapters, among them several that challenge some of the less well-supported orthodoxy in biodiversity conservation.Links to resources can be found at www.case4conservation.com Visit www.case4conservation.com
