read or seen or heard or thought something way too often. I apologize. Several years ago I ran across this video/song by Madison Park called Opus One. It was and still is one of the most powerful combinations of song and imagery I've ever encountered. I would caution you that it is heart-wrenching and overwhelming (at least it is for me).
Here is the link to the video over on youtube if it doesn't work well in the blog post.
The imagery and song were very important for me early in my vegan evolution...I would wish that everyone see and hear it, most especially everyone who is not living as an ethical vegan.
