What movements does EA have the strongest synergies with?

The EA move­ment is strong on its own, but it also res­onates with peo­ple in other move­ments al­low­ing op­por­tu­ni­ties for over­lap, syn­ergy, and shared ac­tion. What other move­ments fit best with EA, even if they are ones that EA doesn’t cur­rent work much with yet? Why?

Note: Please give one an­swer per move­ment, mul­ti­ple an­swers per per­son okay. If some­one has already given an an­swer with a move­ment you have some­thing to say some­thing about, please say it in a com­ment on their an­swer to keep things or­ga­nized!
