Keynote Speakers

Emma Marris is author of the critically acclaimed book Rambunctious Garden: Saving Nature in a Post-Wild World (Bloomsbury USA, 2011), which is essential reading for anyone who cares about the environment. Emma points out the importance of shifting our focus from trying to re-create or return to a lost, primeval Edenic state in Nature to envisioning a new Eden. As humans change every centimeter of Earth, from "what species live where" to its very climate, our strategies for saving nature must change. Her book explains why, and more importantly, how.

Working as a freelance writer based in Columbia, Missouri, Emma has written for Conservation, Wired, Nature Medicine, OnEarth, and Nature on topics ranging from the environment, evolution, energy, agriculture, and food, to language, books and film.
