Kristie Ebi, a public health researcher, discusses the alarming impact of climate change on our food's nutritional quality. She reveals that rising carbon dioxide levels can enhance plant growth but simultaneously deplete essential nutrients in staple crops like rice and wheat. This dual challenge poses significant risks to food security and public health, particularly for vulnerable populations. Ebi emphasizes the urgent need for action to ensure equitable access to safe, nutritious food, highlighting the intersection of climate action and health.
