Because Fox went out of their way NOT to name Agenda 21. They referred to the 1987 UN World Commission on Environment and Development source for the term 'Sustainable Development', and they showed the three interlocking circles of Environment, Economy, and Social Equity, but that's as far as they would go.
Why wouldn't Fox News name UN Agenda 21? What are they afraid of? Are they afraid they'll be called names or not be taken seriously? What a joke. Fox is already called names and not taken seriously by plenty of people. Why wouldn't they name the source of what they're talking about? UN Agenda 21 is a formal agreement signed by President Bush in 1992. The Convention on Biodiversity was ratified by the House and rejected by the Senate. Is this something that we made up? No. So why the coy, sneaky failure to name it?
UN AGENDA 21 IS SUSTAINABLE DEVELOPMENT.
