Canadian copyright guru Michael Geist has posted 30 Days of DRM: 30 Things You Can Do. It’s Canada-specific but you an adopt what he suggests to your locality.
Some of his suggestions:
Ask each political party where it stands on copyright.
Write to your local school board.
Buy online DRM-free alternatives
Write to Library and Archives Canada to ask that it support the preservation of Canadian heritage
To find out why DRM isn’t good check out what wikipedia has to say. Basically DRM can limit access to important documents and limit what you can do with things you buy.
