How to send an email to Yahoo corporation?

Yahoo had an article that I took great offense to. They had a few incorrect facts listed that offended me and many other people I know. In addition while reading threw a few of the comments, it seems as though many people are also blaming me and my fellow farmers for the situation.

So, I did a little research of which the Yahoo writers forgot to do and I would like to show them the correct facts that way they will not make the same mistake again. If you happen to know how to send the corporation or a writer an email that would be greatly appreciated.
Thanks,
HOOAH
