environmental damage

Dear Sir,

I am an architect and (http://maplered.com) I am conducting a web search for a information on Material (http://g654.org) s for use in the home that are environmentally safe. As no Material (http://g654.org) is absolutely clear of environmental damage I consider that compared to most, Stone (http://g603.net) is a very safe Material (http://g654.org) - I am referring in particular to flooring. However there is the argument about damage to land (http://maplered.com) scape. In trying to Counter (http://GialloFiorito.com) this, or set it in perspective as compared with the major environmental and (http://maplered.com) health issues of other Material (http://g654.org) s, I would welcome any information, reasearch statistics examples etc.
Thank you
