The Role (if any) of Humans in the Great Extinction

Thank you for the article.  I was unaware so much merit had been given to that side of the argument.  I have sent it along to some friends who were equally impressed and informed.

Please keep them coming.  Your posts are so informative it makes up for all of the ones with people arguing unanswerable debates. 

Have a great rest of the week.

Glad to be of use, Nige
