High in the northern mountains of Guatemala, near the ancient city of Quetzaltenango, there’s an unusual new venture that is helping transform the way local communities think about the garbage they throw into landfills. It’s also reforming the way people think about nature’s most industrious ecologist: the worm. María Rodriguez, founder of Byoearth is teaching women the value of the red wiggler worm and the use of vermicomposting to support sustainable farming. It’s a concept she believes in passionately and is having increasing success selling to both local farmers and non-profit aid organizations throughout Latin America.
