The purpose of the Prairie Green Party is to advance the Ten Key Values of the Greens through political and non-political means and support the formation of local Green Parties. The Ten Key Values are: Ecological Wisdom, Social Justice, Grassroots Democracy, Nonviolence, Decentralization, Community-based Economics, Feminism, Respect for Diversity, Personal and Global Responsibility, and Future Focus.

To join the party, you can fill out the membership form at http://www.ilgp.org/groups/membership/forms/get_involved. Please indicate "Prairie Greens" as your local on that form.
