We hear from Arizona State University marine biologist Beth Polidoro about her research into plastics in seafood. Polidoro has studied freshwater fish in Arizona and also marine animals in the Philippines to analyze contaminants in fish and other seafood. She also uses that information to help inform consumers of the danger of those contaminants in understandable terms.
In April 1944, Jewish prisoners Rudolf Vrba and Alfred Wetzler miraculously escaped from the Auschwitz concentration camp and fled through Nazi-occupied Poland to find refuge in Žilina, Slovakia, where they connected with the Jewish Underground. Once safe, they recounted what they left behind. Their harrowing testimony revealed the true horror of the Holocaust to the outside world, describing in forensic detail the gas chambers and the full extent of the Nazi extermination program.
