Hey, welcome to the forum-zero waste is such an eye-opener once you dive in! For your PowerPoint, kick it off with a fun hook like the “plastic-free July” challenge I tried last year; it cut my trash by half without feeling deprived. Include real-life wins like swapping single-use coffee cups for a stainless steel tumbler (saves $100+ yearly and keeps drinks hot forever) or DIY upcycling old jars into planters-super visual for slides. Structure it as: problem (waste stats), your journey/experiments, actionable tips, and a call to action for the class. Keeps it engaging! Anyone else got presentation hacks? Let’s brainstorm more.
