The WE ACT grassroots organization Peggy Shephard founded in Harlem, New York City has brought extraordinary benefits to the community: they have transformed the once filthy and decrepit Harlem piers into a gem of a neighborhood park, forced the city to upgrade its entire bus fleet to a cleaner diesel system, spearheaded robust community engagement activities and have led initiatives to bring fresh food and cleaner air to residents of upper New York City. In her TedX talk, Shephard tells about these and other of WE ACT’s fantastic accomplishments.
