U.N. Peace Keeping Armed Forces

In the current world climate, globally we have two problems created and compounded by an every increasing and consuming population of humanity. One is climate change, and the other is resource related wars. This leads to mass displacement, acts violating human rights, species loss, and general mayhem and tragic anarchy. Famine, war, weather extremes and disease are natural checks and balances for the problem, but they are harsh and tragic for all involved, and the innocent (such as other species) are rarely unaffected. Education, cultural evolution (which human rights helps with) and technology (using our brains) are a far less painful way to counteract the potential disasters. Here is an idea to counteract the devastating effects of over-population and resource issues.
The United Nations were formed as a global co-operative after World War II to promote peace between nations and to prevent further man-made disasters such as humungus wars. In many ways it has been effective, as we have not had a major war since. However, there has been many, many more wars of a smaller range, of which the U.N. will attempt to tone down with diplomacy, condemnation and, after the war, international war crimes trials. However, when the heat is on BEFORE the atrocities, the diplomats often have to flee. Many a diplomat or world leader has realised that the U.N. really does need more teeth. It can bark, but it has very little bite. It is an ideal with heart and mind, but has a very light body.
If the armed forces of each and every country donated 1% of there troops, time, money and equipment to the U.N. purely for peace-keeping and natural disaster relief exercises, the U.N. would certainly have a bit more clout. Expecting America to be "the policemen of the world" is a white elephant of dangerous proportions. It tempts the power hungry into a path that is damaging for all. However, there would have to be a system to prevent such a large armed force designed purely for peacekeeping and relief work from being used for less honourable purposes. Firstly, there would be unilateral voting involving all nations of the U.N., with unchangeable laws in that fair system (no nation having a greater vote then another), and also, a right for any nation to remove their troops if they see an exercise to be unfit. So if a dictator attempts to take over the U.N.'s armed forces, the majority could remove their forces and regroup once they have been subdued.
This will free up other U.N. resources for the purposes of education, developing cultural growth, and technological advancement for the greater health and well being of the global citizens, including helping the natural resources be managed responsibly, and helping humanity reach it's greater potential.
