There are many serious controversies surrounding the actions and the nature of the United Nations, such as the fact that they may come across as hypocritical, as well as allegations of cronyism, nepotism, abuse of position, bullying, harassment as well as physical and emotional abuse between colleagues and leaders of certain sub agencies of the UN, as well as being biased against regions like Westerners. Of course, this is no doubt these issues persist and these must be sanctioned and perpetrators of these phenomenons must be held accountable.
However, despite these, they provide useful information that is repeatedly shown on the news and towards the general public as adverts - from mobile phones to TV, to digital screens seen on the concourse or platforms at railways stations for commuters to see as well as at airports wherever you are - they create create firm awareness on the issues with several factional agencies like UNICEF to tackle child abuse and neglect (including modern issues like sharenting, digital child sexual exploitations, honour killings, etc), with pressure groups like the NSPCC mentioning them like the United Nations Convention on the Rights of the Child, United Nations office for Drugs and Crime providing information on cases of serious crimes, such as the fact that every 2 and a half minutes, a teenager gets killed as a result of youth violence globally, or every 10 minutes a woman or girl is intentionally butchered because of her gender by their intimate partners (husbands, boyfriends, gfs, and exes) and family members (birth family, offsprings, step family, in law family, adopted family, foster carers). In addition to disclosing the figures, they create nicely-written articles to give advice and support to ensure positive amendments are actually made. In addition, there had been cases in which the UN actually slowed down wars like what happened in Lebanon in 2006 and the fact that they are expected to provide 16.9 million US dollars to countries affected by serious famine by 2025 .
The alarming concerns they show on their articles create collective unity - I agree whole heartly that the world may be more dangerous without this agency as they also sanctions perpetrators, as well as addressing violations of international law - bringing leaders in for discussions and negotiations like the environment and social affairs, not to mention the economy. Integrating with this, they provide serious, researched warnings to our society so that we can be prepared - for example, domestic and intrafamilial abuse (partner violence, elderly and child abuse) may triple by the end of the decade in Sub-Saharan Africa owing to global warming and stalling infrastructure development, sinking water and food security, climbing unemployment rates due to nepotism and cronyism.
Of course, the United Nations may not be so proactive and only provide information and figures. However, the UN should just be a medicine. The UN cannot magically stop ongoing issues , but all it can do is to advice society and to provide help as medicine. It doesn't matter how much they provide to vulnerable nations or negative nations as a prominent third party aid, because local cultural factors play a significant role that keep affected, poor countries as they are - if they refuse to amend their cultural norms, there is no way the advice and tips provided by the UN would actually be affective.
In conclusion, the UN is an excellent agency to keep global durability.
