Earth Day Network’s newly revised Teach-in Toolkit in celebration of the 50th anniversary provides a history of teach-ins, new digital teach-in tools, steps for hosting a teach-in event, and ideas for how to bring new environmental knowledge into community-based civic action.  The new sections cover how to host impactful digital teach-ins that empower audiences and communities to take on civic action and stewardship activities. The resource is a good tool for bringing your community together and building capacity to make change. For those needing ideas for which topics to cover, the Topic Grab Bag section of the toolkit is a great place to find specific information on teach-ins for plastics pollution, climate change, biodiversity loss, food sustainability, air and water quality, food waste and security, agriculture and deforestation, and flooding and drought. With suggestions on what speakers to invite and calls to action to end with, this toolkit is great for hosting in-person and virtual events alike.
