Disable comment rss feeds for pages in wordpress

I am currently working on the completion of a custom template and my last hurdle is to be able to remove the comments feed link being added to the head of the page.

For example: in firefox when you open any of the pages on my site there is an rss icon, when clicked I am shown 3 options to add to my reader but the last two are related to comments.

The culprits are located in the

<link rel="alternate" type="application/rss+xml" title="Example Title &raquo; Comments Feed" href="http://example.com/comments/feed" />
<link rel="alternate" type="application/rss+xml" title="Example Title &raquo; Home Page Comments Feed" href="http://example.com/home-page/feed" />

I wish to have the main feed, which contains blog posts from the blog area of the site but do not want any comments, therefore comment feeds are useless to me!

I am wondering if there is a way I can remove these via the functions.php or some way through wordpress rather than coming up with another (messier) solution?

Thanks,
Tristan

Add this to functions.php

add_filter('post_comments_feed_link', '__return_null');
