Answer:
The United Nation is an international organisation created in 1945 by 51 countries dedicated to maintaining international peace and security, creating cordial relations among nations, and promoting social development, higher living standards, and human rights.
Because of its unique international character and the powers granted to it by its founding Charter, the Organization can take action on a wide range of issues and provide a forum for its 193 Member States to express their views through the General Assembly, Security Council, Economic and Social Council, and other bodies and committees.
The United Nations' activity covers every corner of the earth. Although the United Nations and its System (specialised agencies, funds, and programmes) are best known for peacekeeping, peace - building, conflict prevention, and humanitarian assistance, there are many other ways the UN and its System (specialised agencies, funds, and programmes) impact our lives and make the world a better place. To achieve its goals and better coordinate for a safe world, the Organization works on a wide range of fundamental issues, including sustainable development, environmental and refugee protection, disaster relief, counter-terrorism, disarmament and non-proliferation, governance, economic and social development, and worldwide health, trying to clear landmines, trying to expand food production, and more.
The United Nations serves four primary functions:
1. To keep the globe at peace;
2. To foster cordial ties between nations;
3. To assist nations in cooperating to better the lives of the poor, to eradicate hunger, sickness, and illiteracy, and to promote respect for each other's rights and freedoms;
4. To serve as a focal point for nations' efforts to attain these goals.
