It isn't the Ukraine war making them scavenge, it's their government putting sanctions on Russia that are only effective at hurting their own people in their own country.

I have central gas fired heat. It has always been to expensive to heat my home in rural CA. I heat with wood. I cut down dying trees, buck and split and stack into cords and season for a year or so. Winter heating bill $0.
