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.
Ban Ki-moonSaving our planet requires you to be ambitious in what you aim, and, equally, in how hard you work to reach your goal.
Ban Ki-moonWe must turn the greatest collective challenge facing humankind today – climate change – into the greatest opportunity for common progress towards a sustainable future.
Ban Ki-moonOur atmosphere can't tell the difference between emissions from an Asian factory, the exhaust from a North American SUV, or deforestation in South America or Africa.
