We are in the beginning of a mass extinction and all you can talk about is money and fairy tales of eternal economic growth

In every great challenge this country has faced, it has turned to the essential strength of its people, united around a common goal.

In the past, human progress had to come at the cost of the environment. If we wanted energy, we had to burn wood or we had to burn fossil fuels. If we wanted to grow more food, we had to expand farmland, often at the cost of forests. But technology and innovation means we're very quickly decoupling these impacts, such that this conflict is no longer true.

We’ll be fine with the environment. We can leave a little bit, but you can’t destroy businesses.

Yesterday’s dams are trying to hold back tomorrow’s climate. And what are we doing about it? We’re building a wall along the Mexican border to fix a problem that’s already taken care of itself. A wall that could cost upward of $30 billion.

We must reject as a nation the false paradigm that if you’re pro-energy you’re anti-environment, and if you’re pro-environment you’re anti-energy.

You are going to be the head of the agency to protect the environment, and your personal feelings about whether climate change is caused by human activity is immaterial?

If Trump turns off the satellites, California will launch its own damn satellites!

Any politically motivated inquisition against federal civil servants who, under the direction of a previous administration, carried out policies that you now oppose, would call into question your commitment to the rule of law and the peaceful transition of power.
