What gives me hope is art - it's the most powerful weapons ever created. It's a weapon of mass construction.

The action we take in the next few years will impact the Earth hundreds of millions of years from now.

Humanity is creating an extinction event that will make every war ever fought a footnote to history. We belong to the only generation in history that can turn this around - we're one step away from greatness or the biggest disaster since the meteor wiped out the dinosaurs.

At the end of the century, humans will look back at our impact on the planet and World War II will be a footnote compared to us presiding over the largest loss of biodiversity since a meteor hit the planet sixty-five million years ago.

If you can reach just 10 percent of the population, you can begin to reach a tipping point; that's where true social movements take place - it's a numbers game. And when you reach that number, the truth becomes obvious and empires of injustice crumble and fall.

Half of all species on Earth could disappear by the end of the century because of our collective impact.

The single most impactful thing you can do today is adopt a more plant-based diet.
