One of the main objectives of the UN is to encourage universal respect for human rights. The Universal Declaration of Human Rights was adopted on 10 December, 1948 by the General assembly.The arms race poses a great threat to the world peace. Our whole planet will be totally destroyed if a nuclear device explodes accidentally or if nuclear war erupts. The arms race is also harmful because valuable resources that could be used for badly needed development purposes, are spent in developing weapons.Great differences exist between the living conditions of people in developing countries compared to those in the developed countries. Degradation of environment is a very serious problem now. We are under threat from various kinds of pollution-air, water and land. Environmental awareness is growing, but the problem can be solved only by passing laws and implementing them effectively.
