Since 1 May 2011, Vegan Outreach has been matching donations dollar-for-dollar, and the matching drive continues through the end of June. One way to donate is to sponsor someone on the Team Vegan page, although contributions to the general fund will be matched as well. I encourage you to donate!
Below is a powerful video about factory farming from February 2011. The information is nothing new, but the footage and presentation is very compelling. Keep in mind, of course, huge quantitative difference between milk/beef and chicken/fish. (You can even observe the contrast visually from the shots of huge numbers of small fish being harvested.)
It's heartening to see how much suffering we can prevent by just a little bit of money donated on our part.
