"I want to say a big thank you to all of you, especially you beautiful young ones. We oldies have made something of a mess of the world. And we want to say to the leaders who are meeting, look in the eyes of your grandchildren. Climate change is already a serious crisis today. But we can do something about it. If we don’t — if we don’t — hoohoo!, hoho! — there’s no world which we will leave to you, this generation. You won’t have a world. You will be drowning. You will be burning in drought. There will be no food. There will be floods. We have only one world. We have only one world. If we mess it up, there’s no other world. And for those who think that the rich are going to escape — hahaha! — we either swim or sink together. We have one world. And we want to leave a beautiful world for all of this beautiful, wonderful young generation. We, the oldies, want to leave you a beautiful world. And it is a matter of morality. It is a question of justice."
