Land… cannot be treated as an ordinary asset, controlled by individuals and subject to the pressures and inefficiencies of the market. Private land ownership is also a principal instrument of accumulation and concentration of wealth and therefore contributes to social injustice; if unchecked, it may become a major obstacle in the planning and implementation of development schemes. The provision of decent dwellings and healthy conditions for the people can only be achieved if land is used in the interest of society as a whole.What better way to take away your house than to set up a situation which would do it - and let them blame you for it? You probably won't protest too much either, if you no longer own anything, if they tell you all land will be used for the "public good".
From The Vancouver Declaration on Human Settlements and the Vancouver Action Plan - A UN Conference held in 1976 - and don't forget Agenda 21.
The UN is dangerous. We need to get out of it.
