PSLA Professor Kate Tully discusses the effects of saltwater intrusion on coastal communities with Special Correspondent Joie Chen on Matter of Fact. Dr. Tully shares her lab's research observations on how salt burns trees from the inside out and how saltwater intrusion has lead to community desertion. Coining the phrase "if you eat, you should care," Tully explains the necessity for people to have a global perspective on what's happening in coastal communities and its effects on the world's food production.
