This really is a big deal.

A brother-in-law was working with a company working with Walmart on this. WalMart has caved in to customer pressure and dedicated themselves to a clean up-stream process. That means all their suppliers will have to verify that THEIR sources are also environmentally 'green'.

Since WalMart controls such a large portion of the market, what they demand will impact all their suppliers who want to continue doing business with them (or just about everybody). These suppliers also service other distributors. Cleaning up their acts so they can sell to one supplier cleans up others, too...
