You can now take an Online Global Poll concerning environmental conditions and policies set up by the company Politics Online for the United Nations World Summit on Sustainable Development being held in Johannesburg, South Africa.

This article from Tech Central Station addresses some of the technical and rhetorical issues affecting this poll's reliability.

Since access to the internet is not even across the globe, there seems to be little effort to obtain a representative sample. Also, the poll is only available in English! I suppose none of this will be a big deal unless the Summit actually places faith in the poll's results.
