Where Can I Find Organic Or Earth Friendly Wholesale Office Furniture?

I would suggest Ikea since they manufacture using soft replaceable woods like pine, birch and mdf and laminated boards that use wood chip and can be recycled easily.
These come in many colours, even mahogany if you do not like pine.
They often have the best  and most innovative designers who produce furniture that meets the needs of the market.
Modern or traditional, unfussy and most importantly affordable and in the quantity that you need to furnish an office.
There is a range for every price bracket in this Swedish company and you will probably
get compliments once it's in place because it does not shout Ikea. It can be made  to blend in with any  interior design scheme in the home or office. I have got compliments, and no I do not work for them
There are Ikea stores all over Europe or you could check out their web site to find your nearest.
I think it is impossible to make furniture without having some impact on the environment, as plastic, glass wood, metal and glues have to be used.
