Agenda 21: Domination

What exactly is Agenda 21 all about and why are so many outraged because of it? Is it a United Nations voluntary consortium or a stepping stone toward a global centralized government? Under the disguise of world sustainability and feeding the hungry, is there an underlying agenda that is not so altruistic as they may have us believe? Monsanto along with other powerful corporations have shown more than an interest in Agenda 21. What use could this be for them and their profit driven GMO biotech science? The possibilities are frightening.
