We regularly fill auditoria with enviro-friendly crowds eager to hear about bugs, blooms, cultivation and conservation. Not surprisingly, the disinterested and skeptics rarely turn up. But shouldn’t those be the very audiences we should try to engage about the need for conservation, the threats posed by invasive species, the urgency of climate change? Come for some inspiration and some laughs as you, the audience, role-play as less supportive listeners; and we, the speakers, try to engage you on touchy subjects. We’ll all learn from each other, glean some tips and avoid the pitfalls associated with speaking to skeptics.
