The Ghost Net Project is aimed at drawing awareness to the impact of human activity in the Northern Gulf of California. The Northern Gulf of California was once one of the richest marine ecosystems on earth. Today its natural resources - from sharks and shrimp to grouper and snails - are in decline.  Proceeds from the purchase of these posters are contributed to this fund, helping CEDO to advance local participation in sustainable fishing practices and in developing an integrated management framework of small-scale fisheries, including the commercial divers Sociedad Cooperativa Buzos de Puerto Punta Peñasco.

Our Ghost Net Project artist, Katherine Larson, has earned yet another accolade for her new volume of poems, Radial Symmetry.  With this book, Larson has created a transcendent body of poems that flourish in the liminal spaces that separate scientific inquiry from empathic knowledge, astute observation from sublime witness.  Larson's inventive lyrics lead the reader through vertiginous landscapes - geographical, phenomenological, psychological.

An experienced research scientist and field ecologist, Larson dazzles the reader with these sensuous poems, grappling with the powers of poetic imagination as well as the frightful realization of ecological destruction. This profoundly moving collection of poems is available through CEDO, supporting both the poet and her favorite conservation organization, CEDO.
