Galbraith Warns "There Is No Planet B" in TEDx Talk

David Galbraith, a University of Arizona professor of plant sciences who holds joint appointments with the Department of Biomedical Engineering and the BIO5 Institute, presented a TEDxUofA talk in spring 2019.

In his presentation, Galbraith explores the sterilizing effects of cosmic radiation and concludes that the preservation of our planet, Planet A, is the only recourse for the survival of humanity, and that "There is no Planet B."     

Galbraith’s research focuses on the hazards and effects that an artificial space environment has on living bodies.
