I can tell you what I am working on, which is being more cognizant of my actions and how they affect others, most I will never meet. I've begun with my purchases. I'm focusing on quality versus quantity - a nicer tee-shirt with organic cotton and buying just one or two instead of five that are cheaper but made with GMO cotton, which is hard on Earth. It's caring a little more beyond myself. And I think it may be our only hope - and it feels much better to my soul, which in the end may be all we have.
If you wear clothing, and put out trash you are using up resources that others also need BUT I can pay attention and I can do better. That I know for sure about me, my soul needs to try or I can't lay my head down on my pillow at night and even hope to sleep.
