Easy social action
Here are two links to do some social justice work from the comfort of your chair in front of your computer:
Save Social Security -- Sojourners, a Christian ministry focused on social justice, has their Call to Action set up so all you have to do is plug in your information and a letter will be sent to your congresspeople telling them that Social Security is "a covenant for the common good."
As someone who gets Social Security disability, I can say that this is important. Really. I don't even want to think of where'd I'd be right now without it.
Tell Wal-Mart Enough is Enough Petition -- a petition set up at the Petition Site which is trying to gather 50,000 signatures to tell Wal-Mart that their warm fuzzy commercials would be a lot more warm and fuzzy if their employees were allowed to unionize, or had affordable health care, or better wages, or better working conditions, or weren't costing state taxpayers millions in welfare benefits for their employees who don't make enough at Wal-Mart, etc.
So, go on. Click, fill in the lines, and know that you've done just a little bit to make the world maybe just a tiny bit better.
