The Green Team

The Groundwork Lawrence Green Team is a year-round program that offers part-time, paid employment for 50 Lawrence high school students each year. Members learn about and lead local environmental and healthy community initiatives, conduct research, grow food, raise awareness, challenge their peers to do community service and participate in hands-on improvement projects throughout the city. The program is intended to promote the protection and restoration of Lawrence’s critical ecological systems, natural resources and public health by engaging teens in advocacy and service-learning focused on the community’s parks, streets, gardens, waterways and vacant open spaces. The Green Team program has dual goals: to prepare Lawrence’s youth for a lifetime of environmental and healthy community leadership, and to invest in Lawrence’s future capacity to improve its physical environment.
