Greetings.
There is a dispute regarding the reference to http://www.earthcharterinaction.org/content/articles/6/1/Congratulations-from-Pope-John-Paul-II-to-Mikhail-Gorbachev-for-his-work-on-the-Earth-Charter/Page1.html that you added to the Earth Charter article on November 18.
Please, make yourself familiar with the contents of the talk (sections "Use of assertions of endorsement, etc. from Earth Charter Initiative as reliable sources" and "The Catholic Conservation Center essay credibility questioned"), and voice your opinion on what justifies inclusion of this reference in the article.
As Wikipedia's principles and practices should be applied to determine if the inclusions are relevant, you might want to read (if you haven't already) the following guidelines: Verifiability, and Reliable Sources. The Wikipedia's core principles are described in the Five Pillars of Wikipedia.
