The Hopkins Celebrates Earth Day 50 Lightning Talk is releasing this week's video titled "Leading by Example: Sustainability in Museums." This Lightning Talk presents some ideas about how assuming the role of leaders can promote our involvement with our communities. The video also considers some options for the extent of our role in promoting sustainable projects and activities to varying degrees, which may include sharing what we do in-house—for example, making better use of our resources to host individuals and institutions that want to come together to develop their own sustainable initiatives.
