The Forest of the Sea: A Conversation with David Helvarg

The Lowell Lecture Series at the New England Aquarium presents award-winning journalist and environmental champion David Helvarg for a talk focused on kelp, climate, and the future of the ocean. Drawing from his book, The Forest of the Sea, Helvarg will recount his memorable two-year journey beneath the waves tracking kelp’s natural and human history in stories that span the globe.

While they cover more space and generate more oxygen than the Amazon Rainforest, kelp forests are largely out of sight and mind, hidden beneath the water. Helvarg will highlight the people working for the understanding, protection, restoration, and edible harvesting of kelp forests and the more than 1,000 species from sea otters to salmon to seadragons—that depend on these incredible ecosystems. He will also discuss the $500 billion of products and services kelp contributes to the global economy, and the human activities that threaten its survival.

Discover what each of us can do in our day-to-day lives to make a difference for the blue planet’s flora and fauna, from both land and sea, that we are all connected to.

This New England Aquarium Lowell Lecture Series event is presented through the generosity of the Lowell Institute. This event is free, but advance registration is required. Doors open at 6:00 p.m. and the program starts at 6:30 p.m.
