Dr. Timothy Krantz, an environmental scientist at the University of Redlands, says the IPBES Global Assessment Summary tells the bigger story of what he knows from his research in California. 

"Each plant and animal has its own story of the causes of its decline — from bald eagles (eggshell thinning from DDT) to mountain yellow-legged frogs (fire, drought, and water diversions) to the unarmored three-spined stickleback (drought, water diversions, development) and an entirely new species of sage that was just bulldozed for a 'fire break' almost to extinction last week before I could even name it."  

Dr. Krantz can speak with authority on a broad scope of topics related to extinction, endangerment, and other issues affecting the environment. He holds a Ph.D. from the University of California at Berkeley, an MA from Stanford University and a BA from the University of Redlands.
