The article says that USA is the only developed country that didn&#x27;t signed an international treaty in e-waste and points to this link:<p><a href="http:&#x2F;&#x2F;www.basel.int&#x2F;Countries&#x2F;StatusofRatifications&#x2F;PartiesSignatories&#x2F;tabid&#x2F;4499&#x2F;Default.aspx" rel="nofollow">http:&#x2F;&#x2F;www.basel.int&#x2F;Countries&#x2F;StatusofRatifications&#x2F;Parties...</a><p>But USA is listed in the page. It has a lot of footnotes: <a href="http:&#x2F;&#x2F;www.basel.int&#x2F;Countries&#x2F;StatusofRatifications&#x2F;PartiesSignatories&#x2F;tabid&#x2F;4499&#x2F;Default.aspx#US16" rel="nofollow">http:&#x2F;&#x2F;www.basel.int&#x2F;Countries&#x2F;StatusofRatifications&#x2F;Parties...</a><p>Would anyone explain in plain English what these footnotes mean, and why the original article says USA didn&#x27;t ratified the treaty?
