With all the challenges of the actual time it seems to be difficult to find actions which are easy as well as effective. What the "leaders" suggest are mainly actions full of  sacrifices and other disagreable "laws".  And even more, these "leaders" create the problems which they then want to solve by restrictions on the individuals. So there is only one solution to this mess: To rely on the own abilities, to hear to the expanded self,  to trust oneself, to do it by the own (expanded) means. Chief Joseph gives some impulses for that  and these impulses are in my opinion very bright:

In your environmental challenges - or any other challenges, personal or global -- go within, whatever that means to you. Could be prayer, meditation, anything that gets you into a peaceful centered place. Trust your inner guidance to show you what to do.

Sometimes you’ll be told to simply hold your planet in your vision and send it love and light. Other times you’ll be guided to take physical action. Do whatever your higher selves guide you to do - or perhaps you’ll be guided to do nothing for now. There is no one "right" way.

Above all know this: One person, acting alone in alignment with her/his higher self, is far, far more powerful than millions of other acting out of fear, anger, rage, revenge

If you have a world full of powerful individuals acting alone and separately, you will create paradise on earth.

If you have a world full of those acting out of fear, anger, rage, revenge, you will continue to create more of the world you have now.
