I thank Columbia University for hosting this gathering — and I welcome those joining online around the world.
We meet in this unusual way as we enter the last month of this most unusual year.
We are facing a devastating pandemic, new heights of global heating, new lows of ecological degradation and new setbacks in our work towards global goals for more equitable, inclusive and sustainable development.
To put it simply, the state of the planet is broken.
Humanity is waging war on nature.
