If you feel individual action is useless, here are links to a few collective actions you can join. Some of these are worldwide movements, others are smaller in scale:
Permaculture A worldwide movement that presents a complete plan for human settlement modeled on natural ecosystems. People often say we need to come up with a plan for how humans can live on Earth without destroying it. This plan already exists and millions of people worldwide are following it. One can start small and take little steps, or one can completely transform one’s life. The links below have been the most helpful to me, but there’s an almost endless amount of information available for free.
