The cultural place-maker Ximena Caminos presents “marine acupuncture,” an innovative practice combining high art and deep science to target critical pressure points within our oceans and fostering environmental awareness through art and action-driven conservation. The ReefLine will be a 7-mile underwater public sculpture park, snorkel trail, and hybrid reef off Miami Beach’s shoreline. Conceived by Ximena Caminos and developed by the BlueLab Preservation Society, the ReefLine nonprofit team collaborates with the architecture firm OMA, as well as marine biologists, researchers, architects, and coastal engineers to design the master plan. Caminos’ lecture, followed by a conversation with Pedro Alonzo and Charles Waldheim, highlights how this pioneering approach uses human ingenuity to ignite ecological processes that regenerate the reef.

Join the Harvard Office for Sustainability and Harvard Common Spaces for an Earth Day Festival on Tuesday, April 22, 2025 from 12 to 2 pm at the Science Center Plaza!

Attend this talk in which Laura A. Schifter and Jonathan Klein highlight the many ways in which K-12 schools and students have tremendous potential to advance solutions on environmental issues, and they provide frameworks for enacting change, in Students, Schools, and Our Climate Moment. Schifter and Klein demonstrate how the effects of climate change intersect with US public schools on multiple levels—for example, schools must prepare students to face the challenges of an uncertain future, accommodate disruptions brought about by extreme weather conditions, and evaluate their systems’ energy consumption and carbon emissions.
