Memberships and Donations

When you join or give to the Sierra Club you will have the satisfaction of knowing that you are helping to preserve irreplaceable wildlands, save endangered and threatened wildlife, and protect this fragile environment we call home. You can be sure that your voice will be heard through congressional lobbying and grassroots action on the environmental issues that matter to you most.  All activities of the Sierra Club are dependent upon contributions from members and supporters like you! With your help, we can continue to offer exciting programs and advocate for sound environmental policy in Oklahoma!

One of the easiest ways to become an activist is to join the Sierra Club, or make a donation.
