Twenty years ago, your freedom was bargained away.

World leaders meeting in 1992 in Rio de Janeiro, with 10,000 junket-winning journalists in tow to ensure media support, created Agenda 21, the United Nations’ grand vision for global “sustainability.”

For sustainability, read domination.

But that’s just paranoia talking.

That’s what liberals will tell you. With the anniversary coming this June, the mainstream media are sure to dish up a healthy dose of panaceas, screeds and excuses, all aimed at convincing you that Agenda 21 is just a well-intentioned suggestion for saving a doomed Earth. The UN has no enforcement power. It certainly has no troops for taking over the world.

Turns out you don’t need an army, just legions of cooperative bureaucrats and populations of brainwashed liberals.

The past 20 years have proved that.

The infiltration of Agenda 21 thinking has been gradual and subtle, but it has borne fruit that has been tremendously damaging to our freedom, our economy and our country.

The plan itself, which is available on the United Nations website, is full of soothing platitudes about rights, preserving resources, economic development and the like. But as is usual with leftist-inspired documents, you have to understand the code to discern the real intent.

Maurice Strong, the Rio summit’s secretary general, spelled it out at the time. He said in his opening speech that ‘current lifestyle and consumption patterns of the affluent middleclass involving high meat intake, use of fossil fuels, appliances, homes or work air conditioning, and suburban housing are not sustainable.’

The Rio Declaration on Environment and Development incorporates and extends Strong’s observations, spelling out the beginnings of what government is expected to do: “To achieve sustainable development and a higher quality of life for all people, states should reduce and eliminate unsustainable patterns of production and consumption and promote appropriate demographic policies.”

The later Johannesburg Declaration, in 2002, reaffirms the Rio summit and spells out exactly who is to implement and enforce the environmental policies: “We assume a collective responsibility to advance and strengthen the interdependent and mutually reinforcing pillars of sustainable development  (economic development, social development and environmental protection) at the local, national, regional and global levels.”

In the 20 years since Rio, that’s exactly what has happened. Federal, state and local policies have regulated, manipulated and re-educated people into accepting the global green agenda.

What have been the results? A world economy on the brink of collapse as energy, food and construction industries are crippled by government interference.

Private property rights are vanishing as homes and farms are foreclosed on.

Oil prices soar, restricting your freedom of travel.

Restrictions on water and agriculture have made food less affordable and of lower quality.

Vast swaths of land that could provide amply for the needs of entire civilizations go unused.

People are being forced out of rural and suburban areas into crowded, crime-riddled cities.

Millions of real, productive jobs have been lost as government expands or promotes phantom green jobs in dead-end industries.

And those “appropriate demographic policies”? Why do you think the United Nations, the U.S. and most other governments are so hot for abortion and contraceptive programs?

Even local governments have blithely bought into the agenda. Plastic bag bans, allegedly aimed at saving animals, take another bite out of the plastics and oil industries. Installation of “smart meters” allows faceless bureaucrats to decide when your house is too cold or too hot, or when you can wash your dishes.

Twenty years after Rio, liberals will tell you that the Earth is still in danger, that more needs to be done.

The reality is, Agenda 21 supporters have done too much already.
