I found this team working toward the same goals!

This site outlines the current state of the cow-feed-seaweed situation. It makes me very excited to find them.

I want to stress that I am not of the belief that we will convince Tyson to start adding seaweed to their feed immediately; the seaweed needs to be grown first! We are spreading awareness and opening a dialogue to make sure corporations are ready to implement this as soon as it is possible to do so. 

We are up to 200 signatures, keep it up!
