Dr Jane Goodall, Scientist & Activist

“It’s not that the world hasn’t had more carbon dioxide, it’s not that the world hasn’t been warmer. The problem is the speed at which things are changing. We are inducing a sixth mass extinction event kind of by accident and we don’t want to be the ‘extinctee.’”

Bill Nye, ‘The Science Guy’

“One can see from space how the human race has changed the Earth. Nearly all of the available land has been cleared of forest and is now used for agriculture or urban development. The polar icecaps are shrinking and the desert areas are increasing. At night, the Earth is no longer dark, but large areas are lit up. All of this is evidence that human exploitation of the planet is reaching a critical limit. But human demands and expectations are ever-increasing. We cannot continue to pollute the atmosphere, poison the ocean and exhaust the land. There isn’t any more available.”

Stephen Hawking, Physicist & Author

I want you to act. I want you to act as you would in a crisis. I want you to act as if the house is on fire, because it is.

Greta Thunberg, 17 year-old Swedish Activist
