I want to thank Mr. Chairman for giving me the opportunity to talk on the environmental issues of today. I am really proud to address this group, as you are at the frontlines of the battle to save the world. Time is not on our side, we need to keep moving forward, and we need to move fast. We’re at a crucial point in the world’s history. Our oceans and forests are suffering, species are disappearing; the climate is changing. Around the world, billions of our fellow human beings lack the most basic requirements of health and dignity.
