Men must teach each other that real men do not violate or oppress women - and that a woman's place is not just in the home or the field, but in schools and offices and boardrooms.

Since problems spill across borders, security anywhere depends on sustainable development everywhere.

Countries with more gender equality have better economic growth. Companies with more women leaders perform better. Peace agreements that include women are more durable. Parliaments with more women enact more legislation on key social issues such as health, education, anti-discrimination and child support. The evidence is clear: equality for women means progress for all.

I believe in a world of justice and human rights for all. A world where girls can grow up free of fear of abuse. A world where women are treated with the respect and dignity that is their right. A world where poverty is not acceptable. My dear young friends, you can make this your world.

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.

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.

Women must be full partners in development, so they can lift themselves and their communities out of poverty.
