Well, since "using" it can be considered actively supporting it, then I suggest you:
-Throw away your computer, ditto your television and your radio;
-move out of your present home and into as remote an area as you can--most likely you're going to be constructing your own home from scratch;
-get acquainted with very basic, very simple hand tools, because that's all you're going to be using for the remainder of your life;
-learn to raise your own food and get used to a very simple, very basic diet, since you're going to be raising everything you eat from here on out, and trying to raise enough of your own food to salt, dry or can for the lean winter months when you can't grow anything;
-learn to make your own clothes from homespun, so goodbye to comfortable clothing
-start getting very, very comfortable with the idea that you and the people you love are going to die much younger than you might have otherwise, and that in all probability you're going to be in a great deal of protracted pain when you do, unless you're lucky enough to die in an accident. Because you're also going to be giving up most modern medical technologies.
