Welcome. Nice to see you have created an account. A few quick comments on your edits: this seems more like something you want to add to the article, not a normal talk page post. See this page for more on talk page guidelines.
At this article you suggest an article on the relationship between plants and animals. Plant ecology and animal ecology are two such articles that should discuss this, though neither of them exist yet. Such is the slow progress of Wikipedia...
I'm not setting the best example myself, but talking about human population problems on an article about mutualism also goes against the talk guidelines. If you'd like to discuss the matter with me it should probably be done outside of Wikipedia, or at least away from article talk pages. Richard001 (talk) 07:53, 30 March 2008 (UTC)
