Rss feed for articles not validating

I am trying to submit my RSS feed for articles to a number of aggregators, however many of them rejsct the feed with the message

RSS feed address did not validate.

 

When I test the feed at FeedValidator

http://feedvalidator.org/check.cgi?url=http%3A%2F%2Fmeetyourgreens.net%2Fm%2Farticles%2Fact_rss%2F

 

I get a number of warnings and errors

 

How can I fix this , as currently I cannot submit to a significant number of sites
