We must follow the wisdom of the Brundtland Report. We must pursue development that meets the needs of the present generation without compromising the ability of future generations to meet their needs.
For my generation, coming of age at the height of the Cold War, fear of nuclear winter seemed the leading existential threat on the horizon. But the danger posed by war to all humanity-and to our planet-is at least matched by climate change.
Nuclear terrorism is one of the most serious threats of our time. Even one such attack could inflict mass casualties and create immense suffering and unwanted change in the world forever. This prospect should compel all of us to act to prevent such a catastrophe.
Energy is the golden thread that connects economic growth, increased social equity, and an environment that allows the world to thrive.
Millions of our fellow human beings continue to live as contemporary slaves, victims of abominable practices like human trafficking, forced labour and sexual exploitation. Countless children are forced to become soldiers, work in sweat shops or are sold by desperate families. Women are brutalized and traded like commodities. Entire households and villages labour under debt bondage.
National boundaries these days are not that important because of transformative technological development. Now we are talking about the fourth industrial revolution.
Today, we have more than 110,000 men and women deployed in conflict zones around the world. They come from nearly 120 countries ... Thanks to their efforts, life-saving humanitarian assistance can be delivered and economic development can begin.
People everywhere look to the United States to use its remarkable power to help lift humanity up and to work for the common good.
Three decades into this crisis, let us set our sights on achieving the "three zeros" zero new HIV infections, zero discrimination and zero AIDS-related deaths.
On this International Day for the Abolition of Slavery let us reaffirm the inherent dignity of all men, women and children. And let us redouble our efforts to build societies in which slavery truly is a term for the history books.
World military spending has now risen to over $1.2 trillion. This incredible sum represents 2.5 per cent of GDP (global gross domestic product). Even if 1 per cent of it were redirected towards development, the world would be much closer to achieving the Millennium Development Goals.
I strongly reject threats by any member state to destroy another or outrageous attempts to deny historical facts such as the Holocaust.
I am willing to take any measures when it comes to the fundamental principle of human rights.
I have been urging the leaders to listen to the aspirations and challenges of their own people, and engage in dialogue and take very bold measures. Normally, to their regret, these measures and bold reforms come too late, too little.
I call for the need of world leaders to address climate change and reduce the increasing risk of disasters- and world leaders must include mayors, townships and community leaders.
Millions of people in nearly 80 countries still live in fear of landmines and explosive remnants of war, which take an unacceptable toll on lives and limbs, and people's livelihoods
Gender equality and women's empowerment have been a top priority for me from day one as Secretary-General. And I am committed to making sure that the U.N. leads by example.
I am not a national leader. If I am a national leader I can speak out all that I want.
Climate change is destroying our path to sustainability. Ours is a world of looming challenges and increasingly limited resources. Sustainable development offers the best chance to adjust our course.
Since [violence against women] is rooted in discrimination, impunity and complacency, we need to change attitudes and behavior - and we need to change laws and make sure they are enforced just like you are doing in Cuba.
The international community cannot accept that whole communities are marginalized because of the color of their skin. People of African descent are among those most affected by racism. Too often, they face denial of basic rights such as access to quality health services and education. Such fundamental wrongs have a long and terrible history.
To achieve a Green Revolution, African farmers, must have access to land and security of tenure. They also need access to markets, technology and improved infrastructure.
The international community must offer short-term emergency measures to meet critical needs. But it must also make longer-term investments to promote food production and agricultural development, enhance food security and maintain and accelerate momentum towards the MDGs.
Since problems spill across borders, security anywhere depends on sustainable development everywhere.
Climate change, demographics, water, food, energy, global health, women's empowerment - these issues are all intertwined. We cannot look at one strand in isolation. Instead, we must examine how these strands are woven together.
