Unfortunately, the war machine is in overdrive and lots of wicked parties are using media propaganda to escalate emotions amongst people. The only outcome of this high temperature is more war and suffering for all, which again benefits the wicked parties (military corporations and others), while regular people everywhere will suffer.
So write to your government, turn off the media, and if you believe, pray for peace. That is the best way to help.
The best anyone can do to make the world better place is support the world again the Russian aggressors and war criminals. People "asking for peace" and "deescalating" are just on the side of the aggressors and war criminals.
Don't behave like the real world is a Marvel movie filled with heroes and supervillains. If you truly want to help, write to your govt representative. Anything else you do as a civilian or private business is vigilantism, and will have no impact on the actual conflict at hand.
