The Nature Conservancy

I’ve been a member off and on for several years. Recently, I realized that they have a local office right in downtown Seattle, and I think this would be a great place to volunteer for, as they have worked for years to protect wildlife habitat – forests, lakes, grasslands, rivers – here in the U.S. and around the world.
Going to the Woodland Park Zoo is nice as an outing for the family, but we really all can do more for the survival of our planet Earth.
Membership fees are pretty low. You can also be part of their online community (free) and stay connected that way.
(They also send you sheets of neat little rectangular address stickers with a tiny picture of an endangered species and your name and address (to use as a return address on an envelope).
