These are various groups and projects that I've found motivating, exciting, and/or generally worth supporting over the years. Many have actionable resources as well, including financial donation options.
Editorial Note: While donation is a worthwhile form of material support, I've chosen to de-emphasize that particular avenue; I'm of the opinion that more good comes about when people put effort into our own learning and direct action for justice, versus sending off some donations to feel like "we helped" - it is far too easy for a donation receipt to become an excuse to not examine our own responsibilities for making things better. For those with the means, I highly recommend exploring mutual-aid networks as a way to both give and make direct, meaningful impacts.
