Let's Talk Sustainability, or LTS, is a youth development program that supports high school youth to develop expertise regarding sustainability, online broadcasting, and virtual world construction. Global Kids youth in New York City combined this expertise to produce talk shows that will feature live interviews with scientists and other STEM-related professionals, pre-produced videos, and audience activities. LTS introduced Global Kids youth to a broad range of concepts related to the topic of sustainability including energy, urbanization, pollution, biodiversity, global warming, and food justice. Youth selected three subtopics to research and designed talk shows to address each one. Each show iss designed to introduce youth audiences to what professionals are doing in these fields and showcase what youth can do to live in a more sustainable world.
