The United Nations is central to global efforts to solve problems which challenge humanity. Cooperating in this effort are more than 30 affiliated organizations, known together as the UN system. Day in and day out, the UN and its family of organizations work to promote respect for human rights, protect the environment, fight disease, foster development and reduce poverty. UN agencies define the standards for safe and efficient transport by air and sea, help improve telecommunications and enhance consumer protection, work to ensure respect for intellectual property rights and coordinate allocation of radio frequencies. The United Nations leads the international campaigns against drug trafficking and terrorism. Throughout the world, the UN and its agencies assist refugees and set up programmes to clear landmines, help improve the quality of drinking water and expand food production, make loans to developing countries and help stabilize financial markets. One of the UN's central mandates is the promotion of higher standards of living, full employment and conditions of economic and social progress and development. As much as 70 per cent of the work of the UN system is devoted to accomplishing this mandate. Guiding the work is the belief that eradicating poverty and improving the well-being of people everywhere are necessary steps in creating conditions for lasting world peace. The UN has unique strengths in promoting development. Its presence is global, and its comprehensive mandate spans social, economic and emergency needs. The UN does not represent any particular national or commercial interest. When major policy decisions are taken, all countries, rich and poor, have a voice.
